Cerium(4+) tetrahydroxide(CAS: 12014-56-1)

Cerium(4+) tetrahydroxide (CAS: 12014-56-1) is a white or pale yellow solid with a crystalline form. Its molecular weight is approximately 269.98 g/mol. It is slightly soluble in water and slightly reactive with acids. Cerium(4+) tetrahydroxide has a low melting point and is stable in dry air but decomposes in moist air or water.

Cerium(4+) tetrahydroxide (CAS: 12014-56-1) can be synthesized by the hydrolysis of ceric salts in the presence of sodium hydroxide or potassium hydroxide. Common methods include the precipitation of cerium(IV) ions from a solution of cerium(IV) nitrate or cerium(IV) chloride with sodium or potassium hydroxide. The reaction is typically carried out at room temperature or slightly elevated temperatures, with a yield of around 85-95% depending on the purity of starting materials and reaction conditions.

Cerium(4+) tetrahydroxide (CAS: 12014-56-1) is used in various industries, including catalysis, where it serves as an efficient catalyst for several chemical reactions. It is also used in the manufacturing of ceramics, glass, and pigments due to its color stability and resistance to thermal shock. Additionally, it has applications in semiconductors and as a polishing agent in optical and electronic devices.

When handling Cerium(4+) tetrahydroxide (CAS: 12014-56-1), it is important to wear appropriate personal protective equipment (PPE) such as gloves, safety goggles, and a lab coat. It should be handled in a well-ventilated area or a fume hood to avoid inhalation of dust. Spills should be cleaned up using appropriate absorbent materials and disposed of according to local regulations. Always refer to the Safety Data Sheet (SDS) for detailed handling instructions and emergency procedures.
