Application
Solar photovoltaic, chemical, thermal (e.g. etching groove, window, support plate, reaction chamber base, cover plate).
The high purity quartz sand is directly fused and drawn, with high flatness, small thickness deviation, almost no bubble cutting deviation, almost no bubble and flexible dimension production. Especially high processing utilization, is the optical, chemical and other fields of high quality extruded quartz materials.
He formation of quartz flakes is due to the high viscosity of the melt at high temperature. It is widely used in semiconductor, electro-optic source, semiconducting communication device, laser, optical instrument, laboratory instrument, electrical equipment, medical equipment, high temperature and corrosion resistant chemical instrument, chemical industry, electronics, metallurgy, building materials and national defense industry.
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.
Optical properties editing.
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.
