    • A process for preparing strengthened ferroelectric ceramics, which comprises sintering ceramic materials and then heat treating the sintered ceramics at a temperature from about 100.degree. to about 400.degree.C lower than the final sintering temperature of ceramics, for about 1 to about 60 hrs., and then cooling at a rate from about 300.degree. to about 10.degree.C per hour. Strengthened ferroelectric ceramics are obtained among the following ferroelectric ceramic compositions:I. pb([B.sub.1 ].sub.A Ta.sub.1.sub.-A)O.sub.3 --PbTiO.sub.3 --PbZrO.sub.3, where [B.sub.1 ] is Mg, Zn, Cd, Sn, Mn, Fe, Co, and Ni when A=1/3 and [B.sub.1 ] is Li and Cu when A=1/4,Ii. pb([B.sub.2 ].sub.B Ta.sub.1.sub.-B)O.sub.3 --Pb([B.sub.3 ].sub.C Ta.sub.1.sub.-C)O.sub.3 -PbTiO.sub.3 -PbZrO.sub.3, where [B.sub.2 ] and [B.sub.3 ], [B.sub.2 ].noteq.[B.sub.3 ], are Mg, Zn, Cd, Sn, Mn, Fe, Co and Ni when B and C=1/3, and [B.sub.2 ] and [B.sub.3 ], [B.sub.2 .noteq.[B.sub.3 ], are Li and Cu when B and C=1/4,Iii. pb([B.sub.1 ].sub.A Ta.sub.1.sub.-A)O.sub.3 PbTiO.sub.3 --PbZrO.sub.3 with MnO.sub.2, where [B.sub.1 ] is Mg, Zn, Cd, Sn, Fe, Co and Ni when A=1/3, and [B.sub.1 ] is Li and Cu when A=1/4, andIv. pb([B.sub.2 ].sub.B Ta.sub.1.sub.-B)O.sub.3 --Pb([B.sub.3 ].sub.C Ta.sub.1.sub.-C)O.sub.3 --PbTiO.sub.3 --PbZrO.sub.3 with MnO.sub.2, where [B.sub.2 ] and [B.sub.3 ], [B.sub.2 ].noteq.
