Quartz glass has two kinds of transparent and opaque quartz glass. Transparent and opaque quartz glass is the most economical material used in industry and scientific research.
The raw materials used for its manufacture (by melting method) are crystal or high purity, ultra-high purity quartz sand (transparent quartz glass) and white quartz sand (opaque quartz glass).
Both of these materials exist in nature and are made up of the purest SiO 2.
Quartz glass and crystal have the same chemical composition, but their structures are quite different. One is in the glass state, the other is in the crystalline state. Crystal can not withstand high temperature thermal shock, it will break down and transform into other crystal metamorphosis at high temperature, while quartz glass can withstand extremely high temperature impact.
The manufacture of transparent and opaque quartz glass requires high temperature because crystalline SiO 2 can not melt until it is above 1713 degrees Celsius.
