Phosphoric acid, calcium salt (1:) Usage And Synthesis

Description

Tribasic calcium phosphate occurs in nature as minerals, oxydapatite, whitlockite, voelicherite, apatite, phosphorite. It has many industrial applications. Some are similar to the monobasic and dibasic salts. It is used in fertilizers, dental products, ceramics and polishing powder. Some other important applications are in plastics as a stabilizer; as an anticaking agent; as a nutrient supplement in cattle food; for clarifying sugar syrup; as a mordant in dyeing textiles; and as a buffer to control pH.

Preparation

Tribasic calcium phosphate is obtained from naturally occurring minerals for fertilizer applications. The compound may be prepared in the laboratory by the reaction of sodium phosphate with calcium chloride with excess of ammonia. Also, it can be prepared by treatment of calcium hydroxide with phosphoric acid:
2H3PO4 + 3Ca(OH)2 → Ca3(PO4)2 + 6H2O

Chemical Properties

White crystals or amorphous powder. Slightly soluble in water (solubility 0.0025g/100ml water), easily soluble in dilute hydrochloric acid and nitric acid, insoluble in ethanol and acetone.

Definition

ChEBI: Tricalcium bis(phosphate) is a calcium phosphate.

Agricultural Uses

Calcium phosphate [Ca₃(PO₄),] is a white insoluble powder and is the main constituent of bones. Calcium phosphate occurs naturally as rock phosphate in the mineral apatite Ca₅(PO₄)₃,which contains OH^-, F^- and Cl^- ions to a small extent.
Calcium ions and hydrogen phosphate ions react inthe presence of an alkali to produce calcium phosphate.
Calcium phosphate is used extensively as a fertilizer.Dicalcium phosphate is a common constituent ofnitrophosphate fertilizers and of compound fertilizersformed by ammoniation of superphosphates. Calciningof phosphate rock, sodium carbonate and silica in a rotarykiln at 1250°C gives rhenania, or calcium sodiumphosphate.
