Cerium stearate

[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.
