Abstract

The inﬂuence of synthesis conditions on the formation and character of sintering of nano- and polycrystalline ceramic materials based on solid solutions of the four-layer Aurivillius phase type (Bi1‒xCax)5FeTi3O15‒δ has been studied. It is shown that the beginning of grain sintering correlates with the beginning of melting of the surface phase. The inﬂuence of the synthesis method on the crystallization temperature and the beginning of sintering, as well as on the TCLR of the obtained materials, is determined.

Keywords

Aurivillius phases, perovskite-like complex oxides, nanocrystals, polycrystalline ceramic materials,
