| Abstract: | Specific heats CEp of some phosphates have been measured on powder samples, in the temperature range 100–373 K. Anomalous behaviour of CEp (T) has been observed for Co(H2PO4)2 2H3PO4 and Mn(H2PO4)2 2H3PO4 around 190 K. In triclinic Ba(H2PO4)2 a phase transition was found at about 147 K, i.e. at a somewhat higher temperature than according to previous dielectric measurements. |
