product description

Chemical Identity: Calcium phosphate monobasic (CAS#10031-30-8), also known as monocalcium phosphate monohydrate, is an inorganic calcium phosphate with the formula Ca(H₂PO₄)₂·H₂O.


Physical and Chemical Properties: The material is typically supplied as a white crystalline powder or granules, depending on the grade. It contains calcium and phosphorus and produces acidic aqueous solutions.


Grade-Specific Applications: Depending on the grade, it is used in food leavening systems, animal feed formulations, and phosphate-based chemical preparations. Food and feed uses require material meeting the relevant application specifications.


Quality Specifications: Quality parameters may include assay, calcium and phosphorus content, moisture, insoluble matter, and relevant impurity limits. Detailed specifications and batch results should be confirmed through the product specification and certificate of analysis.

Product Description of Calcium phosphate monobasic CAS#10031-30-8

Ammonium phosphates comprise monoammonium orthophosphate, diammonium orthophosphate and ammonium polyphosphate. They are produced by direct reaction of anhydrous ammonia with orthophosphoric acid or superphosphoric acid. The products are dry crystalline solids with favorable handling performance, suitable for storage, transportation and industrial processing.


Product Application of Calcium phosphate monobasic CAS#10031-30-8

Diammonium phosphate is widely used as an efficient compound fertilizer for vegetables, fruits, rice and wheat, providing nitrogen and phosphorus nutrients. It also acts as a feed additive for livestock and ruminants, a yeast nutrient and a water softening agent. In industry and laboratories, it is used as an analytical reagent and buffering agent, and applied in printing plates, pharmaceuticals and electronic components. In the food industry, it serves as a leavening agent, dough conditioner, fermentation additive and pH buffer. Furthermore, industrial-grade diammonium phosphate is used in flame-retardant formulations, dry powder fire extinguishers, wood and fabric impregnation, fluorescent phosphors, wastewater treatment, as well as special fireproof and military insulation materials.
