FAQ

What are the physical and chemical properties of Calcium hydroxide phosphate (CAS: 12167-74-7)?

Calcium hydroxide phosphate (Ca5(OH)(PO4)3) is a crystalline compound with a high molecular weight. It has a low solubility in water and is moderately reactive with acids and bases. This compound is amphoteric, meaning it can act as both an acid and a base under certain conditions. It is insoluble in organic solvents. CAS: 12167-74-7

How is Calcium hydroxide phosphate (CAS: 12167-74-7) typically synthesized?

Calcium hydroxide phosphate is typically synthesized by reacting calcium oxide with phosphoric acid in a controlled environment. The reaction is exothermic and can be carried out using various stoichiometric ratios. The process involves careful temperature and pH control to achieve the desired yield and purity. CAS: 12167-74-7

What industries use Calcium hydroxide phosphate (CAS: 12167-74-7)?

Calcium hydroxide phosphate (Ca5(OH)(PO4)3) is used in pharmaceutical formulations, as a precursor in the synthesis of other phosphates, and in the production of certain polymers. It also finds applications in the development of sensors and as a component in some semiconductors. CAS: 12167-74-7

What precautions should be taken when handling Calcium hydroxide phosphate (CAS: 12167-74-7)?

When handling Calcium hydroxide phosphate (CAS: 12167-74-7), wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work in a well-ventilated area or a fume hood to minimize inhalation risks. Avoid contact with acids and bases, as it can react with them. In case of a spill, clean up with care following standard safety protocols. Always refer to the safety data sheet (SDS) for specific handling instructions. CAS: 12167-74-7
