The manufacturing process of quartz glass directly determines its performance grade and application field. The manufacturing of quartz glass can be divided into two primary processes: the melting process, which uses natural quartz as the raw material, and the synthesis process, which uses silicon-containing compounds. The former includes traditional methods such as electric melting, gas [...]
The presence of transparent components in a laboratory, a semiconductor production line, or optical equipment often indicates the utilization of quartz glass. Material costs have never been a single consideration. The value of this material is attributable to its hidden properties, including high-temperature resistance, light transmittance and chemical stability. Key reasons semiconductor and optical industries choose quartz glass In [...]
Quartz (fused silica, SiO₂) has a melting point above 1700 °C; therefore, at 110 °C there is absolutely no risk of physical melting. The frit structure remains intact. However, chemical corrosion is a separate concern. Quartz is an acidic oxide and can be slowly attacked by alkaline solutions, especially at elevated temperatures. K₃PO₄ (tripotassium phosphate) [...]
