Zircon is a silicate mineral, which is the main ore for extracting the metal zirconium. Zircon is widely found in acid igneous rocks, but also occurs in metamorphic rocks and other sediments. The chemical properties of zircon are very stable, so gem grade zircon can also be seen in the gravel of the river. There are many kinds of zircons, different zircons will have different colors, such as red, yellow, orange, brown, green or colorless transparent and so on. When cut, gem-grade zircon looks like a diamond. Zircon used to be called zircon or hyacinth. Zircon can withstand high temperatures above 3000 ° C, so it can be used as an insulation material for spacecraft. Artificial zircon, chemical name: cubic zirconia

Advantages of Zirconium:

　　1. Burn resistance, high thermal conductivity.
