3.Application: Metallurgy and Chemical industry,Fused quartz,Building and Grind
Introduction
Silica Quartz is is the most common silica mineral, its main content is SiO2, specific density 2.65g/cm3, hexagon crystal, lump or powder form. Appearance color: colorless, white, cyan gray. It's a high quality quartz smelting process through a unique form processing, Its crystal structure orderly transition from disorder to order, products with high whitness,stable chemical property,uniform particle size distribution,better mobility,coefficient and good electromagnetic radiation.
Size: 4-6mesh, 6-10mesh, 10-20mesh, 40-70mesh, 100-200mesh, 270mesh, 325mesh, 400mesh, 500mesh
Packing: 500KG/ Bag or1000 kgs/ Ton Bag with double layers or as customer's requirement
