Product Description
Zircon Sand

Zircon Sand Description

Zircon sand, also known as zircon sand and zircon, is a mineral composed mainly of zirconium silicate (ZrSiO4). Pure zircon sand is a colorless transparent crystal. It is often dyed yellow, orange, red, brown, etc. due to different origins and different types and types of impurities. The crystal structure is tetragonal and has a quadrangular pyramid shape.
Features
Zircon Sand Characteristic : Zircon sand is a mineral composed of zirconium, silicon and oxygen crystallized from magma, mainly formed by igneous rocks. Zircon is also produced in the veins and metamorphic rocks. It is a tetragonal system, often in the form of a well-developed cone-shaped small square cylinder, which is also irregularly granular.
Product Application
Zircon Sand Application :
Zircon sand (zircon) is used inrefractory materials, foundry sands, precision enamelware, and in the production of glass, metal and zirconium compounds. It can make zircon bricks from glass kiln, zircon bricks, ramming materials and castables for steel drums.
Zircon Sand is extremely resistant to high temperatures and has a melting point of 2,750. And resistant to acid corrosion. 80% of the world's direct use in the foundry industry, ceramics, glass industry and the manufacture of refractory materials. A small amount is used in ferroalloys, pharmaceuticals, paints, leather, abrasives, chemicals and nuclear industries. A very small amount is used to smelt metal zirconium.
