Quartz products

Quartz products mainly refers to many products made of quartz glass. Mainly including quartz glass tube, quartz glass rod, quartz glass, quartz glass mound, fused quartz glass tube (furnace core tube), fused quartz glass rod, quartz glass boat, quartz glass crucible, etc.

The raw materials from the purity of 99.5% or more refined quartz sand, refined quartz sand: SiO2 ≥ 99-99.5% Fe2O3 ≤ 0.02-0.015%, selected high-quality ore from the complex processing.

    Particle size range with 5-480 mesh, according to user requirements, the appearance of white or crystalline. Main purposes: advanced glass, glass products, refractories, smelting stone, precision casting, grinding wheel and other grinding wheel.

   Quartz products are the main raw materials for high-purity quartz sand and fused silica sand, the main physical and chemical properties are as follows:

High purity quartz sand: SiO2 ≥ 99.5-99.9% Fe2O2 ≤ 0.005%, is the use of 1-3 natural crystal stone and high-quality natural stone, after careful selection, fine processing from Particle size range of 1-0.5mm, 0.5-0.1mm, 0.1-0.01mm, 0.01-0.005mm, according to user requirements.

Fused silica sand: Chemical composition:

SiO2 99.9-99.95% Fe2O3 5PPM-25PPM max Li2O 1-2PPM max Al2O3 20-30PPM max

K2O 20-25PPM max Na2O 10-20PPM max (PPM is one millionth of a unit)

Physical properties:

Appearance is colorless and transparent lumps, granules or white powder.
