High quality Rare Earth oxides products supplier

Yttrium oxide is a highly stable compound with a high melting point and is very inert chemically. Yttrium oxide is also known to possess excellent plasma-tech and erosion resistance, particularly in plasma containing halogen species.
 

Thermal spraying coating

Yttria caoting used on chamber walls and tooling for semiconductor manucturing, which are typically applied by atmospheric plasma spray, must be of high purity, high particle size control.
