Ytterbium Oxide Purified 99.9%

Ytterbium oxide white powder, but it show tawny if containing a few thorium oxide. Except lutetium oxide, It has weakest alkaline among yttrium group. Ytterbium trioxide slightly absorb moist in air and turn to ytterbium subcarbonate. It dissolve in dilute acid, but not in water and cold acid.

Ytterbium Oxide

Applications

Ytterbium oxide mainly apply to make magnetic bubble material of computer, which make magnetic bubble storage high speed, high capacity,  small volume, multifunction.

It is raw material for preparing permanent magnet material, optical glass, pigment for ceramic, laser material, catalysts and chemical additive.

Ytterbium trioxide is raw material for fluorescent powder and coversion luminescent material. It is additive for radio ceramic, dielectric ceramic, special alloys and quartz fibre.

Magnesium Sulfide LAB GRADE 99%

Magnesium sulfide is colorless to brown crystal powder, which is sulfide of magnesium. It is of sodium chloride type structure and the chemical property is similar to other  ionic type sulfide compounds as sodium sulfide, barium sulfide and calcium sulfide. Magnesium metal and pure sulfur are the raw materials.  It dissolve in diluted hydrochloric acid, however MgS crystal react with water slowly.

Magnesium Sulfide

Applications

Magnesium sulphide can apply to do desulfurization for iron and steel and making fluorescent powder.  It can apply as a semiconductor with wide band gap.
