Application
The optical properties of quartz sheet are unique. It can not only transmit far ultraviolet light, but also transmit visible light and near infrared spectrum. Because of its high temperature resistance, small thermal expansion coefficient, good chemical stability, bubble, stripe, uniformity and birefringence, quartz glass is an indispensable optical material with high stability optical coefficient in various harsh conditions.
Product Feature
The flame ingot is made by flame 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. PQ871S/E series is with even higher impurity level.

Physical Property
Quartz sheet is a special industrial technical glass made of silica, which is a very good basic material. Quartz flakes have a series of excellent physical and chemical properties, such as:
1. High temperature resistance. The softening point of quartz glass is about 1730 ℃. It can be used at 1100 ℃ for a long time, and the maximum temperature can reach 1450 ℃ in a short time.
2. Corrosion resistant. In addition to hydrofluoric acid, quartz glass hardly reacts with other acids. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel, especially its chemical stability at high temperature, which is unmatched by any other engineering materials.
3. Good thermal stability. It can adapt to the extremely small coefficient of thermal expansion of glass, and can withstand the drastic temperature changes. When the quartz glass is heated to about 1100 ℃, it will not burst when it is put into normal temperature water.
4. Good light transmittance. The transmittance of quartz is over 93% in visible light, especially in ultraviolet spectrum, the maximum transmittance is over 80%
