8P + 3Ca(OH)₂ + 6H₂O = 2PH₃ + 3Ca(H₂PO₄)₂
2P + 3Ca = Ca₃P₂
Ca₃P₂ + 6H₂O = 3Ca(OH)₂ + 2PH₃
4P + 5O₂ = 2P₂O₅
2P₂O₅ + 3H₂O = 2H₃PO₄
2H₃PO₄ + 3Ca(OH)₂ = Ca₃(PO₄)₂ + 6H₂O
Ca₃(PO₄)₂ + 6HCl = 3CaCl₂ + 2H₃PO₄
P₂O₅ + 3CaO = Ca₃(PO₄)₂
2Ca₃(PO₄)₂ + 10C + 6SiO₂ = 4P + 10CO + 6CaSiO₃
3P + 5HNO₃ + 2H₂O = 3H₃PO₄ + 5NO
