DEFINITION
Quartz glass is a glass consisting of almost pure silica (silicon dioxide, SiO2, above 99.9%), produced by melting high-purity silica sand at high temperature (2,000℃ or higher)
Characteristics
Thermal Shock Resistance
- Quartz glass has a high melting point and extremely low coefficient of thermal expansion
Wide Transparency Range
- Quartz glass has a wide transparency range which can extend well into the ultraviolet and into the infrared as well as visible ray
Quartz glass has a high physical strength.
Chemical Inertness
Quartz glass is chemically inert to most element including virtually all acids,
regardless of concentration, except alkali.
