Method for preparing high-density silicon nitride ceramic through multi-factor optimization and prepared silicon nitride ceramic
The invention provides a method for preparing high-density silicon nitride ceramic through multi-factor optimization and the prepared silicon nitride ceramic. According to the invention, by optimizingcold isostatic pressing molding, pre-sintering, hot isostatic pressing sintering process, composition, total content and other test parameters of a binder and a sintering aid, and adopting multi-factor optimization, the density of silicon nitride products is improved, the problem that the existing silicon nitride ceramic products are difficult to obtain parts with high density ( greater than 99.5%) is solved, and the produced silicon nitride product not only has high density ( greater than 99.5%), but also has extremely high strength. The excellent performances determine that the high-densitysilicon nitride ceramic can be more widely applied in the fields of aviation, aerospace, precise high-speed bearings, electronic packaging and the like
本发明提供一种通过多因素优化制备高致密度氮化硅陶瓷的方法及制备的氮化硅陶瓷，本发明优化冷等静压成型、预烧结、热等静压烧结工艺和粘结剂、烧结助剂的成分及总含量等试验参数，采用多因素优化，提高氮化硅制品的致密度，解决了现有氮化硅陶瓷产品难以获得高致密度(>99.5％)件的问题，所生产出的氮化硅产品不仅具有高致密度(>99.5％)，也具有极高的强度，这些优异的性能决定了高致密度的氮化硅陶瓷在航空、航天、精密高速轴承、电子封装等领域将有更为广泛地应用。
