It has been reported by our previous paper on the sintering behavior of lead zirconate titanates (PZT) that additive MnO promotes the grain growth and suppresses the densification of PZT. This paper reports the sintering behavior of PZT with various amount of additive MnO and Sb<SUB>2</SUB>O<SUB>3</SUB>. Additive MnO promotes the grain growth of PZT, while additive Sb<SUB>2</SUB>O<SUB>3</SUB>, supresses the grain growth even with additive MnO together. It was found, however, that Sb<SUB>2</SUB>O<SUB>3</SUB> acts as a sintering aid in the case of sintering PZT with 0.5 mass% Sb<SUB>2</SUB>O<SUB>3</SUB> at 1100°C: this condition attains the maximum density of all the specimen. It also revealed that the grain boundary diffusion is dominant in PZT with no additive or with only MnO, and that volume diffusion is dominant in PZT with only Sb<SUB>2</SUB>O<SUB>3</SUB> or the both of Sb<SUB>2</SUB>O<SUB>3</SUB> and MnO.
