WebPRODUCTION AND CHARACTERISTICS Triple superphosphate is a soluble phosphate fertilizer containing about 20% total P (44-48% P 2 O 5). Besides P, TSP also contains 13-15% calcium (Ca), and a maximum of 4% residual phosphoric acid (H 3 PO 4). The concept of superphosphate fertilizer production is relatively simple, involving the addition of ... Web23-109 The present invention is concerned with a process for the manufacture of dicalcium phosphate. It is known to produce dicalcium phosphate (CaHPO by adding secondary sodium phosphate (Na HPO to a neutral calcium-salt solution. Another method of obtaining Cal-IP0 is to precipitate it by means of Na i-IP0 from a solution of primary … current carrying capacity of copper cables
