Ca3 (PO4) 2 → P → H3PO4 → K3PO4
1) 2Ca3 (PO4) 2 ↓ + 10C + 6SiO2 = 4P + 10CO + 6CaSiO3 ↓ (calcium orthophosphate, carbon, silicon dioxide, phosphorus, carbon oxide (II), calcium silicate);
2) 2P + 4H2O = 2H3PO4 + H2 ↑ (phosphorus, water, phosphoric acid, hydrogen);
3) H3PO4 + 3KOH → K3PO4 + 3H2O (phosphoric acid, potassium hydroxide, potassium orthophosphate, water).
