Production 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.
Raw Material Introduction
The polished quartz plate is made by electrical drawn method with raw material of PQ own purified natural quartz sand. Continuous flame melting produces highly purified, net formed quartz ingots with few micro-bubbles (high material utilization ratio), which can be processed into various shapes. PQ161 series is with even higher impurity level.
