1. Combustion of phosphorus:

P4 + 5O2 = P4O10 (P2O5).

2. Formation of phosphoric acid:

P2O5 + 3H2O = 2H3PO4

3. Obtaining calcium phosphate:

2H3PO4 + 3Ca (OH) 2 = Ca3 (PO4) 2 + 6H2O.

4. Reaction of fusion with coke:

2Ca3 (PO4) 2 + 10C + 6SiO2 = 6CaSiO3 + P4 + 10CO.

5. Obtaining calcium phosphide:

2P + 3Ca = Ca3P2.
