摘　　要：将不同团聚态钼粉混合后进行压型、预烧及烧结。对压型中孔洞的形成原理及在后续预烧结、烧结中的演变进行了探索研究,结果表明,硬团聚钼粉在压型中难于破坏而易于形成原始孔洞,这种空洞在预烧中不能消除,在烧结中容易形成分层的内部缺陷。The molybdenum powder with different agglomeration state was mixed, then the mixed powder experienced pressing 、 pre - sintering and sintering. The truth which holes came into being during die - pressing and developed in pre - sintering and sintering was researched. The results displayed hard agglomeration molybdenum powder was difficult to destroy during pressing, so it is easy to pile into primary holes for them, they couldn＇t disappear during pre - sintering and formed separation in inner plate during sintering.
