Paper Title:
Charactering and Sintering of BaZrO3 Doped with TiO2
  Abstract

The high sintering temperatures required for solid-state derived powders is a significant obstacle inhibiting more widespread use of single pure phase BaZrO3 with high density. The aim of this research was to reduce the sintering temperature whilst maintaining pure single phase BaZrO3. By using of sintering aid, such as TiO2 additive, the pure perovskite BaZrO3 powder have been fabricated with the solid state chemistry at 1250°C. Low levels of TiO2 (3%) produced the pure BaZrO3 particles with the smallest size, and the corresponding sintered ceramic has the density of 95% theoretical using sintering temperature as low as 1550°C. The microstructure of the particular ceramic with full density confirmed that the particle grain in ceramic block have shaped with the less pore and connected thickly.
