The physical and chemical properties: Orange red needle crystal, very lively, easy with oxygen, nonmetal oxide, water, acid reaction. Corrosive; Water imbibition.

Application:

Cesium oxide can be used in the infrared signal detection equipment, such as the image intensifier photocathode, vacuum photodiode, photomultiplier tubes and television camera tube LR kohler description of the first modern photoelectric emission surface layer on the cesium 1929-30 as a cesium oxide layer on layer of silver and this is a good electron emitter, but its high vapor pressure limits its usefulness.

The preparation  : Cesium in air combustion, mainly produce the cesium, peroxide as only a small amount of cesium oxide and super cesium oxide generated. When the metal cesium is dew in the air, it will quickly oxidation, lose metallic luster, and produce a series of colored oxide.

Elemental magnesium reduces caesium oxide to elemental caesium, forming magnesium oxide as a side-product:

Cs2O + Mg → 2Cs + MgO

Cs2O is hygroscopic, forming the corrosive CsOH on contact with water.

Package:50 kg/drum, inner double plastic bag; Or 50 kg/bag, double plastic bag; Can also according to customer requirements packaging.
