Spark Plasma Sintering Behavior of Shell-core Al2O3-Y2O3 /ZrB2 Composite Powders

ZrB2具有优良的物理特性和化学稳定性而应用于许多领域,但是ZrB2难以烧结致密和在高温条件下容易被氧化.为了充分发挥ZrB2的优点,改善ZrB2的缺点,本文采用共沉淀法制备壳核式Al2O3-Y2O3 /ZrB2复合粉体,通过放电等离子烧结法制备高致密的ZrB2-YAG陶瓷.在相同实验条件下得到的纯ZrB2陶瓷的相对密度都很低,在85%以下.通过此种方法加入少量YAG后,烧结密度得到明显提高,随YAG添加量的增加相对密度增加.添加量超过30wt%后,可以达到几乎完全致密的ZrB2-YAG陶瓷.
