PRODUCTS THAT ARE FORMED BY HEATING AT VARIOUS TEMPERATURES CALCIUM PHOSPHATE AND THORIUM PHOSPHATE (in Italian)

Thorium phosphate reacts with calcium phosphate at a temperature higher than 500 deg C to form thorium oxide and calcium pyrophosphate. The formation of the metaphosphate is also possible. This reaction explains why all the attempts to synthesize apatite by means of high temperature reactions, with tetravalent elements in isomorphous substitution with calcium, as with U/sup 4+/, leads to the formation of the oxide of the element.
