quartz glass plate is a kind of special glass that only contains a single component of silicon dioxide. The quartz glass sheet is made by smelting, cutting and grinding quartz, and its silicon dioxide content can reach more than 99.99%. The hardness is seven grades, and it has the characteristics of high temperature resistance, low thermal expansion coefficient, thermal shock resistance and good electrical insulation performance. Usually colorless and transparent, the visible light transmittance is above 85%.
This optical rectangular quartz sheet usually needs to be customized according to the drawing, because the proportion of the length and width of the fused quartz glass sheet will vary greatly from user to user. As a supplier of quartz plates, we have the ability to customize according to the drawing, and look forward to cooperation.
Quartz glass can be divided into two categories, fused silica glass and synthetic silica glass, from the production scope. Heat resistance, light transmittance, electrical insulation, and chemical stability are all very good.
