Investigations on the Textured Bi3NbTiO9 Ceramics via Spark Plasma Sintering
This paper reported results of an investigation aiming at finding what affected the orientated grain growth of Bismuth titanate niobate (Bi3TiNbO9) by spark plasma sintering process (SPS). Single phase of textured Bi3TiNbO9 (BTNO) ceramics were prepared by a two-step sintering method: synthesizing seed-crystal platelets by molten-salt method with oxide mixture as precursors and then sintering the platelets under different SPS conditions such as heating rate, holding time, sintering temperature and pressure, etc. The possible effects of these factors upon the textured microstructure have been analyzed in detail. Textured Bi3TiNbO9 ceramics with different orientation degree was obtained by controlling the conditions during SPS process.
