Cerium stearate is a metal-organic compound, a salt of cerium and stearic acid with the chemical formula C
54H
105CeO
6. [2] [3] The compound is classified as a metallic soap, i.e. a metal derivative of a fatty acid. [4]
Cerium stearate is synthesized from the reaction of cerium oxide with stearic acid in an inert atmosphere at temperatures between 100 and 200 °C. [5] It can also be obtained by the reaction of cerium nitrate and potassium stearate. [6]
The compound forms a white powder which is insoluble in water.[ citation needed ]
The compound is used in a variety of industrial and laboratory applications: as a lubricant, antioxidant, and antifoaming agent. Other uses include as a catalyst in the synthesis of polymers and as a stabilizer in the production of plastics. [5]
