Quartz Disc
Characteristic
High purity, chemical resistance,
High temperature resistance,
Heat shock resistance,
Low thermal expansion
1.SiO₂ purity: 99.99%
2.Operating temperature: 1250℃.
3.Softening temperature: 1730℃.
4.Quartz glass has good transmittance for infrared and ultraviolet bands, and is suitable for use as a window.
Application
Except for hydrofluoric acid, quartz glass will not react chemically with acid. The acid stability is 30 times that of ceramics and 150 times that of stainless steel. Especially the chemical stability at low temperature is unparalleled.
Good insulation
Coating or plating can be carried out according to customer requirements.
254nm ultraviolet light transmittance can reach more than 85%
Products can be customized according to customer requirements 2mm*2mm*T0.3mm~1400mm*1400mm*T50mm.
Passed CE, ROHS, SGS certification.
