The Feature Of Quartz Crucible

Quartz crucible, with high purity, strong heat resistance, large size high precision, good heat insulation, energy saving, stable quality and other advantages, more and more widely used. The inspection of the quartz crucible is a very important step, and the detection of the quartz crucible is developing towards the field!

Quartz crucible can be used below 1450 degrees, divided into two kinds of transparent and opaque. The translucent quartz crucible fabricated by arc method is the basic material for drawing large diameter monocrystalline silicon and developing large-scale integrated circuits. Today, the world's semiconductor industry developed countries have replaced the small transparent quartz crucible with this crucible. He has high purity and strong heat resistance, large size high precision, good heat insulation, energy saving, stable quality etc..

Can not touch the HF and, at high temperature, and carbonate was easily caustic and alkali metal.

Quartz crucibles are suitable for melting samples with K2S2O7, KHSO4 as flux, and using Na2S207 (first drying at 212 degrees) to treat samples with flux.

Quartz brittle, easy to break, use should pay attention to.

Except HF,

Attention should be paid to the use of quartz crucible

Quartz crucible should be fed according to its capacity, so as not to squeeze too tightly, so as to prevent metal from thermal expansion and cracking of quartz crucible.

Place it in a dry place after use. Do not let rainwater invade.

When removing the molten metal, scoop it out with a spoon and use as few calipers as possible. If using calipers and other tools should be in accordance with the shape of the quartz crucible to avoid excessive local force and shorten the service life.

The service life of quartz crucible is related to its usage. It is necessary to avoid strong oxidation flame spraying directly on the quartz crucible and make the raw material of quartz crucible short-lived.

Introduction to the process of quartz crucible

Slurry Production Process
Slurry molding has a long history in the production process of ceramics, is traditional and relatively easy to master, and is the most common production molding method used today. The slurry method is commonly used in the production of quartz crucibles. The general production process of the slurry method has the following steps. First, is injection molding. Second, disengage the mold. Third, flip. Fourth, curing. Fifth, initial inspection. Sixth, repairing. Seventh, drying. Eighth, calcination. Ninth, trimming. Tenth, final inspection. Finally, packaging. The main supporting production equipment of injection method production includes stainless steel mold, cantilever suction cup crane, curing oven, preliminary inspection line, cantilever suction cup crane, less air dryer, cantilever suction cup crane, calcining oven, cantilever suction cup crane, trimming machine, cantilever suction cup crane, final inspection into the billet table, final inspection turning machine, light inspection rotary table, light final inspection table, final inspection out of the billet line, cantilever Suction cup crane, etc.

Injection Coagulation Process
The injection molding method has just emerged in the production of quartz crucibles, and the process is relatively difficult and not easy to master, so it is relatively little used in the production process of quartz crucibles. However, compared with the injection method, this method can greatly reduce the time to detach the model and improve the efficiency of detachment, which has certain advantages in mass production. Due to its advantages in mass production, it is the future development direction of the production process. The general production process of the injection coagulation method has the following steps. First, is injection molding. Second, disengage the mold. Third, flip. Fourth, initial inspection. Fifth, repair the blank. Sixth, drying. Seventh, calcination. Eighth, trimming. Ninth, final inspection. Finally, packaging. The main supporting production equipment of the condensation method includes stainless steel mold, cantilever suction cup crane, preliminary inspection line, cantilever suction cup crane, less air dryer, cantilever suction cup crane, calcining furnace, cantilever suction cup crane, trimming machine, cantilever suction cup crane, final inspection into the billet table, final inspection turning machine, light inspection rotary table, light final inspection table, final inspection out of the billet line, and cantilever suction cup crane.

Comparison Of The Two Processes
The two processes for producing quartz crucibles are now compared. Since the injection molding method relies on the gypsum mold to absorb water for drying, longer time off the model and lower productivity. The solidification method uses a steel mold, but the product is equipped with an additive in the product ingredients, and the blanks can be solidified quickly during the production process to improve the strength, and it is easy to release the mold quickly, and the strength of the blanks is higher after the release, and it does not need to be cured through the curing oven. However, in the calcination process, these organic additives will decompose and volatilize, thus reducing the density and strength of the product.

What Are The Functions Of Quartz Crucible

The quartz crucible can be used in 1450 degrees, and lit two lit points. Arc discharge method, the semi transparent quartz crucible is pulling large diameter single crystal silicon, to carry out large scale integrated circuit essential foundation materials. Today, the world semiconductor industry in developed countries has used this crucible instead of small transparent quartz crucible.

Quartz crucible suitable for use K2S2O7, KHSO4 and Na2S207 as flux melted samples (first drying at 212 degrees) as flux sample.

Quartz brittle, easy to break, the use should pay attention to.

Except for HF, the quartz glass crucible can be used as a cleaning solution.

The common drawing for single crystal silicon quartz crucible 18 inches and 20 inches have 22 or more manufacturers to use crucible. Now the 18 and 20 inch crucible technology, which is produced by domestic crucible manufacturers, is a sophisticated technology. Its production and use of quartz sand is mainly imported from the United states. Domestic production of quartz sand purity are not up to its request. The material in the impurities in the production of high temperature melting process to produce black bubble on the drawing of single crystal silicon is its stability is bound to affect the.

What Precautions Should Be Taken When Using A Quartz Crucible?

Safety Clothing And Equipment: Always wear proper safety clothing and equipment when working with molten metal to protect yourself from any potential hazards.

Remove Moisture: Before using a crucible, ensure that any residual moisture is removed slowly from the crucible and/or furnace refractories. This can be done by pre-heating the crucible to a high temperature to burn off any impurities.

Avoid Introducing Moisture Or Volatile Materials: Make sure that no moisture or volatile materials are introduced into the melt, as this can cause the crucible to crack on heating.

Clean Crucibles: When using crucibles for chemical analysis, it is essential to ensure that they are clean and free from any contaminants that could affect the accuracy of the results. Pre-weigh the crucible and its lid with high precision to obtain accurate results.

Handle With Care: Use properly fitting tongs to handle crucibles to protect them from damage or failure. This will also ensure your safety when taking samples and avoid damage to the furnace.

Close Furnace Door During Use: The furnace door should be closed during use to prevent damage to the parts. It can be opened slightly if necessary.

Do Not Open The Furnace Door At High Temperatures: Do not open the furnace door after the temperature exceeds 600 degrees. Wait for the temperature in the furnace to cool down before opening the door to avoid burns.

Transfer Heated Crucibles To A Desiccator For Cooling: After heating, transfer the crucible to a desiccator for cooling. This will prevent any potential accidents or burns.

Use Appropriate Crucibles For Different Metals: It is advisable to use different crucibles for different types of metals to avoid contamination. This will ensure the purity of the metal being melted.

Completely Empty The Crucible After Each Use: Make sure to completely empty the crucible after each use to prevent any expansion of solidified metal on re-heating, which may lead to the destruction of the crucible.

Temper The Crucible Before Usage: "Tempering" the crucible before usage can help remove any moisture in the crucible. Heat the empty crucible to a temperature of about 500 degrees Fahrenheit and hold it for 20 minutes. Then work the crucible to red heat, turn off the heat, and leave the crucible to cool slowly. This process prepares the crucible for use.
