high quality white quartz silica sand

Super White Silica sand

Properties:

1. SiO2> 99.99%, high purity quartz

2. Operating Temperature: 1250℃

    Soften Temperature: 1730℃ 
3.Excellent visual and chemical performance.
4. without surface coating
5. Health care and environmental protection
6. Any dimension can be made.
7. CE RoHs SGS approved.

Application:

1. High temperature resistance glass can work under 1200°C continuously, and in short time can even work under 1450°C, its softening point is 1730°C.
2. Quartz glass will not react chemically with acid except hydrofluoric. Acid-stable is 30 times of ceramic and 150 times of stainless steel. Especially chemical stability is incomparable at low temperature.
3. Electric insulation.
4. Excellent thermal shock stability
5.High transmission above 85%
6.Widely used in semiconductor, lighting and electric heating industries.
