Cerium Oxide With Large Particle Size CeO2 CAS 1306-38-3 D50 Greater than 20um

Large particle size cerium oxide (CeO₂) is an important inorganic compound with a yellowish or yellowish brown color. Its high density, high melting point, and insoluble in water and alkali, slightly soluble in acid. Due to its large particle size, large particle size cerium oxide is particularly good in polishing materials, and is often used in the polishing of glass, ceramics, gems and other fields, which can significantly improve the finish of the workpiece. In addition, it can also be used as a catalyst, ultraviolet absorber, fuel cell electrolyte, etc., in environmental protection, energy and other fields have a wide range of applications. However, large particle size cerium oxide may be poor in the efficacy of transdermal action on free radicals, so it is less used in skin care anti-aging.

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.
