摘要

采用氯化物水溶液共沉淀法制备氧化钇稳定型氧化锆粉体。结果表明,共沉淀凝胶的预煅烧工艺对粉末的微观结构、冷压性能和烧结性能有较大的影响。在低至1300°C的烧结温度下,理论相对密度达到+98%。

Characteristics and sintering behaviour of zirconia ultrafine powders

Coprecipitation from water solution of chlorides was used to obtain yttria-stabilized zirconia powders. It was shown that precalcination processing of the coprecipitated gel greatly affects the microstructure of the resultant powder as well as its cold compaction behaviour and hence its sinterability. Relative densities of +98% theoretical have been achieved at sintering temperature as low as 1300°C.
