Thorium Orthophosphate, Th 3 (PO 4) 4 Follow @Atomistry Thorium Orthophosphate is practically insoluble in water and only sparingly soluble in dilute acids; its formation therefore serves partially to separate thorium from other metals occurring in monazite sand, whose phosphates are more soluble in dilute sulphuric acid.

The chemistry of thorium phosphate reported in the literature has been found to be erroneous. It was reconsidered in terms of careful chemical preparations and specific analytical methods. Special attention has been paid to the atom ratio value referred to r = thorium/phosphorus, which was experimentally fixed in order to obtain the correct composition of the final compound.
