What are the functions of quartz glass rods?
Quartz glass rods are mostly used in laboratories. They are used to stir the liquid without damaging our hands or the test liquid itself. Therefore, they are used more frequently. The glass rods can be divided into many types according to different materials. Quartz glass rod is one of them. The quartz glass rod has the following functions:
1. Dissipate the heat evenly
2. Transfer of liquids and solids
3. Diversion of the transfer liquid in the case of filtration, etc.
4. Used for stirring in the case of dissolution, evaporation, etc.
5. Initiate a reaction, such as igniting red phosphorus
Quartz glass rod-matters needing attention
1. When stirring, stir in one direction (clockwise or counterclockwise is fine).
2. Don't use too much force when stirring, so as not to break the glass rod or container (such as beaker, etc.).
3. Don't hit the wall and bottom of the container when stirring, and don't make any noise.
Quartz in a broad sense also includes high-temperature quartz and coesite. Quartz is one of the main rock-forming minerals, generally refers to low-temperature quartz, which is a relatively widely distributed mineral in the quartz group of minerals. Hardness 7, no cleavage, conchoidal fracture. The specific gravity is 2.65. Pure quartz is colorless and transparent. It has a variety of colors due to the presence of trace pigment ions or finely dispersed inclusions, or the existence of color centers, and the transparency is reduced. With piezoelectricity. Quartz is a mineral composed of silicon dioxide with the chemical formula SiO2. Quartz block, also known as silica, is mainly the raw material for producing quartz sand, and it is also the raw material for quartz refractory and firing ferrosilicon. With glass luster, the fracture surface is grease luster. The main component is SiO2, which is colorless and transparent, often containing a small amount of impurities, and becomes translucent or opaque crystals with hard texture. Quartz is a mineral resource with very stable physical and chemical properties. The crystal belongs to the oxide mineral of the trigonal crystal system.
