　　◆  Spraying large sphere yttrium oxide and yttium fluoride particles

　　Mainly used in Microelectronics Seal Cutting Machine, Plasma etchingmachine, , high- temperature fuel cell’s solid electrolyte and electrode coating, and oxygen sensitive sensor’s electrolyte and electrode coating.

Production index: (1) Product purity: 99.9% -99.99% (2) Product particle size: 20 um≤d50≤30um；30 um≤d50≤40um；40 um≤d50≤50um。

　　◆Rare earth additives in Refractory material

　　Rare earth composite additives were added into refractory material, in order to reduce traditional refractory material’s sintering temperature, improve the product’s compressive strength and apparent porosity. In addition, the material’s mechanical and thermal properties were improved. It is mainly used in industrial refractory material, arrester module, flame retarded coating and some other areas.

　　Rare earth additives’ technical index: (1) d50≥10ｕm; monomer’s nanowhiskers length-diameter ratio is between 15 to 35; (2) specific surface area≥30 m²/g.
