摘　　要：研究了烧结助剂和添加量及烧结温度对氮化硼、氧化锆复合粉体在热压烧结过程致密化的影响。结果表明,材料的致密化开始于1750℃,1830℃完全致密。显微结构分析表明,氧化锆和杂质相镶嵌在氮化硼层状基质中。所研制的材料用作薄带连铸用侧封板。The effect of the additives and its amount on the densification of BN-ZrO2 composite powder body during hot pressing sintering were investigated. The densification of said composite started at 1750℃ and ended at 1830℃. Microstructure investigation showed that the zirconia and impurity phases were dispersed in the BN layer matrix. The said composite could be used as side dame materials for the thin strip continuous casting process.
