What is the quartz products?

Release date:2014-06-11 00:00 Source:http://www.hongweishiying.com Views:

Quartz products mainly refers to the number of quartz glass material products. Mainly consists of quartz glass tube, Shi Yingbang, quartz glass, quartz glass, fused quartz glass tube weight (the furnace core tube), fused quartz glass, quartz glass boat, quartz glass crucible, quartz bell jar etc.
The raw materials come from more than 99.5% purity of refined quartz sand, quartz sand refined: SiO2 ≥ 99 - 99.5% Fe2O3 ≤ 0.02 - 0.015%, selection of high-quality ore is complex and processing.
Main uses: advanced glass, glass products, refractory materials, smelting stone type, precision casting, grinding material etc.. The main raw material of quartz products are of high purity quartz sand and fused silica sand, the main physical and chemical properties are as follows:
The high pure quartz sand: SiO2 ≥ 99.5 - 99.9% Fe2O2 ≤ 0.005%, is the 1 - 3 grade natural crystal stones and high quality natural stone, carefully selected, fine processed.
The high pure quartz sand: SiO2 ≥ 99.5 - 99.9% Fe2O2 ≤ 0.005%, is the 1 - 3 grade natural crystal stones and high quality natural stone, carefully selected, fine processed. Particle size range of 1 - 0.5mm, 0.5 - 0.1mm, 0.1 - 0.01mm, 0.01 - 0.005mm, can be produced according to user requirements.
