Procedure

Typically, the predetermined amounts of the aqueous solution of phosphoric acid, the calcium oxide containing product, e.g. the unslaked lime and the CMS are selected in a proportion to produce CMS-enriched calcium phosphate having a total phosphorus content of about 10-18% (mass/mass), a total calcium content of about 8,5-32,4% (mass/mass), and a Ca:P ratio (mass/mass) of between 1,8-1 and 0,85:1.
