The processes occurring during the mechanoactivation of powders and firing of samples pressed from calcium phosphate nanopowders with molar ratio Ca/P = 1.25 were studied. As a result of washing nanopowder in distilled water and alcohol after mechanoactivation ammonium phosphates were removed and only hydroxyapatite and tricalcium phosphate were present in the ceramic. To preserve the molar ratio Ca/P = 1.25 in the ceramic washing should not be performed, and then after firing, aside from the indicated phases, calcium pyrophosphate is also present in the ceramic.
