Description

Argon is a colorless, odorless, monatomic gas that is 1.4 times denser than air, or 10 times as dense as gas. Argon is a kind of amorous gas, at room temperature and other substances do not react chemically, at high temperature is not soluble in liquid metal, in the welding of non-ferrous metal can show its superiority. It can be used for bulb aeration and arc welding of stainless steel, magnesium, aluminum, etc. that is “argon welding”.

Application

Also used in semiconductor manufacturing process chemical vapor deposition, crystal growth, thermal oxidation, epitaxy, diffusion, polysilicon, tungstate, ion implantation, current carrier, sintering, etc.

Oxygen is used in the glass industry, and high-purity oxygen is used in electronics manufacturing.

Argon gas is mainly used in welding, stainless steel manufacturing, smelting.
