Volume III/28 is a supplement to volume III/16a+b "Ferroelectrics and Related Substances". It also consists of two parts a and b. The present subvolume III/28a contains data on ferroelectric oxides, supplementing III/16a which appeared in 1981. Subvolume III/28b, due in 1990, will cover non-oxides, supplementing III/16b (published in 1982). Reliable data on both pure compounds and solid solutions, published mostly between 1978 and 1986 and some data from the literature up to early 1988 are critically evaluated and included. The dielectric and ferroelectric behaviour, as well as all other...

Data on ferroelectric and antiferroelectric behaviour of pure compounds and solid solutions are critically evaluated and in addition all other properties relevant to the characterization of these crystals are presented in tables and figures. Subvolume A is for oxides and B for non-oxides including liquid crystals. This subvolume consists of a printed version and an electronic version on CD-ROM. All the compiled data can be found on the CD-ROM. The abundance and diversity of the data, however, make an overview of the relevant research field difficult, and thus the printed version is designed...
