    Phosphorus forms mostly covalent bonds. Any phosphorus rock can be used for the production of elemental phosphorus. Crushed phosphate rocks and sand (\(\ce{SiO2}\)) react at 1700 K to give phosphorus oxide, \(\ce{P4O10}\): \[\ce{2 Ca3(PO4)2 + 6 SiO2 \rightarrow P4O10 + 6 CaSiO3} \label{1} \] \(\ce{P4O10}\) can be reduced by carbon:
