Because of the above excellent physical and chemical properties, it is widely used in many areas, for example, electric light sources, semiconductors, optical communications, defense industry, metallurgy industry, building materials, chemistry, machinery, electric power, and environmental protection etc.
Besides, the temperature of the fused silica synthesis and cooling rate will affect its crystal structure which will consequently affect refractive index [4].
