Cerium Sulfide powder is a red to dark brown crystalline powder with the molecular formula Ce₂S₃, a density of 5.02 g/cm³, a melting point of approximately 1890°C, insoluble in water, and has potential for many applications.
Properties
Appearance: Usually a red to dark brown crystalline powder.
Density: Relatively high density of about 5.02 g/cm³.
Melting point: High melting point, around 1890°C, but the range of melting points mentioned in the literature varies slightly, some sources suggest it may be in the range of 1890 – 2100°C.
Solubility: insoluble in water.
Stability: Cerium Sulfide is relatively stable in air, but slightly hydrolysed at room temperature in humid air, releasing hydrogen sulfide.
Reactivity: reacts readily with acids.
Semiconductor properties: Cerium Sulfide has semiconductor properties, with a band gap of about 2.06 eV and a high Seebeck coefficient, so it has potential for application in the field of thermoelectric materials.
Pigment properties: Bright colours, good colouring power, covering power and excellent light resistance, heat resistance, weather resistance and chemical resistance.
Applications
Pigment field: it can be used as a kind of high temperature pigment, which is an excellent substitute for heavy metal inorganic pigments such as cadmium red, and is used for colouring plastics, paints, inks, paper, ceramics, sculptures and other industries.
Semiconductor materials: Due to its semiconductor properties, it can be used in the manufacture of electronic devices and optical devices, such as laser diodes, optical filters, X-ray scintillators and other optical devices.
Ceramics: as a dopant for ceramic materials, it can improve the electrical and mechanical properties of ceramics.
Catalysts: Cerium sulphide nanoparticles can be used as catalysts for chemical reactions such as hydrogenation of carbon dioxide and water decomposition.
Lubricant field: with its low coefficient of friction and high thermal stability, it can be used as a solid lubricant.
Solar cell field: Cerium sulfide nanoparticles can be used as sensitisers in dye-sensitised solar cells to improve the efficiency of solar cells.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
