Detailed Description

High Purity Cerium Oxide Powder cas no 1306-38-3 formula CeO2 for glass or areospace area Cerium oxide Powder 99.95%Min 99.995%Min 99.999%Min Light yellow or yellowish brown powder. The density is 7.13g / cm3. The melting point is 2397 degrees centigrade. It is insoluble in water and alkali, and is slightly soluble in acid. At 2000 temperature and 15Mpa pressure, hydrogen peroxide can be used to reduce cerium oxide to obtain three oxidation of two cerium, and the temperature is free at 2000 degrees. When the pressure is free at 5Mpa pressure, cerium oxide has a yellowish reddish and pink color, and its performance is polishing material. Detailed name: cerium oxide; cerous oxide Molecular formula: Ce02 Molecular weight: 172.13 CAS: 12014-56-1 Specifications: According to the purity: low purity: purity is not more than 99%, high purity: 99.9%~99.99%, ultra high purity more than 99.999% According to grain size, it is divided into coarse powder, micron grade, sub nanoscale and nanoscale Safety instructions: the products are non-toxic, tasteless, non irritating, safe and reliable, stable in performance, and do not react with water and organic matter. They are high quality glass clarifying agents, decolorants and chemical auxiliaries. High purity cerium oxide is also used in the production of thin luminescent materials.
