| Abstract: | The present contribution reports on the preparation of BaTiO3 powders in various ways including the characterization and the sintering behaviour. The powders were synthesized by using precursors like BaTiO(C2O4)2 · 4 H2O and BaTiO2(O2) · 3 H2O, or by an alcoholate/hydroxide method, by a successive precipitation from solutions with following thermal treatment, or by the conventional route from BaCO3 and TiO2. The thermal decomposition of the precursors to BaTiO3 is described. The different sintering behaviour of BaTiO3 compacts is the consequence of granulometric properties and of their content of impurities. Possible sintering mechanisms are discussed. |
