Cerium sulfide include cerium(III) sulfide and cerium monosulfide, which are both rare earth metal sulfides. Dicerium trisulphide and cerium mosulfide are both yellow powder of cubic crystal system. Cerium trisulphide could be reduced to cerium mosulphide by silicothermic process. Ce₂S₃ and Si powder react in vacuum furnace and cerium mosulphide would get too. Cerium hydride (CeH₃) is the raw material. Cerium sulphide powder is a new kind of non-toxic red pigment, which has properties as dark red color, strong tinting strength, hiding power, good thermal stability, non-toxic, lead-free, cadmium-free and so on. It is raw material for pink pigment ( ZrSiO₄ coated Ce₂S₃), red pigment (ZrO₂ coated Ce₂S₃), red pigment (SiO₂ coated Ce₂S₃) for low temperature ceramic production. Nano cerium sulphide could reach 85% tinting strength of cadmium red (cadmium selenide), which is better than other inorganic red pigments as iron oxide red, molybdate red. Its opacity is same to cadmium base paint.

Cerium Sulfide

Applications

Cerium sulphide gets widespread application in ceramics as pigment. It is also raw material for a kind of ternary heterostructure, SnS₂-Ce₂S₃–CeO₂, which could be appplied to photocatalytic hydrogen generation and raise hydrogen evolution rate, 0.24mmol at highest.
