Specification
Calcium dihydrogenphoshate , its cas register number is 7758-23-8. It also can be called Calcium superphosphate ; and Acid calcium phosphate . Calcium dihydrogenphoshate (CAS NO.7758-23-8), a major component of phosphate rock such as phosphorite,apatite, and other phosphate minerals, is too insoluble to be an efficient fertilizer. The result is hydrated to turn the calcium sulfate into the dihydrate gypsum and sold as superphosphate of lime. Alternately phosphate rock may be treated with phosphoric acid to produce a purer form of monocalcium phosphate and is sold as triple phosphate.
