Quartz glass is made of high purity silica as the raw material, after forming and sintering process (or arc fusing method) to obtain a stable crystalline phase structure, it has the characteristics of high temperature resistance, excellent optical performance, good corrosion resistance, good thermal shock resistance and oxidation resistance, it is widely used to produce crucbile, optical instruments, devices for semiconductor manufacture. Material composition and fabrication process have significant influence to the quartz performance, according to the application scenario and parameter requirements, material composition and appropriate fabrication process can be selected.
