ABSTRACT:
There is provided a method of producing a ceramic represented by the general formula of ABO.sub.3, wherein A includes Pb and at least one element selected from the group consisting of Ba and Sr and B is either of Zr or both of Zr and Ti, by hot-pressing a complex oxide obtained by calcining the mixture of the oxides of A and B characterized by that a solid solution of the oxides of Ba and/or Sr and the oxide of the element constituting B, such as BaTiO.sub.3, SrZrO.sub.3 or (Ba, Sr)ZrO.sub.3, is used as the starting oxides of Ba and/or Sr, and that the starting material contains PbO in an amount of 3 - 20 mol% in excess of that calculated for the objective composition of the final product. Ceramics produced by the method of the present invention have ferroelectric properties and are optically transparent.
