Name: Cerium Oxide With Large Particle Size CAS: 1306-38-3
Molecular formula: CeO2 D50 SED: 20-30um
Description: Ceria with large particle size is a light yellow powder with large particle size, high specific gravity and good fluidity. It is obtained by chemical precipitation method, specifically taking cerium chloride solution as raw material, adding a certain amount of hydrazine salt additive, oxalic acid as precipitant, nitric acid and oxalic acid mixed solution to wash or soak cerium oxalate precipitation, combined with slow heating and burning, it can obtain large specific surface area and large particle size cerium oxide.
