Large Size Quartz Cylinder
The hardness is 6.5 grades of Mohs, and it has the characteristics of high temperature resistance, low thermal expansion coefficient, thermal shock resistance and good electrical insulation performance.
Quartz
Quartz sheets, usually smelted and cut by quartz, have a silica content of over 99.99%. The hardness is 6.5 grades of Mohs, and it has the characteristics of high temperature resistance, low thermal expansion coefficient, thermal shock resistance and good electrical insulation performance.
It is usually colorless and transparent, and its visible light transmittance is 85% or more.
