High-performance large-size silicon nitride ceramic ball as well as preparation method and application thereof
The invention relates to the technical field of silicon nitride ceramic balls, in particular to a high-performance large-size silicon nitride ceramic ball and a preparation method and application thereof. The invention provides a high-performance large-size silicon nitride ceramic ball. The high-performance large-size silicon nitride ceramic ball comprises the following preparation raw materials in parts by weight: 10-15 parts of silicon powder; 90 to 100 parts of silicon nitride; the mass content of alpha-phase silicon nitride in the silicon nitride powder is 95-99%; 3 to 4 parts of MgO; 1 to 1.5 parts of CeO2; 0.5 to 1 part of Y2O3; and 1 part of TiC. The four-component sintering aid is compounded, so that the compactness of the silicon nitride ceramic material can be effectively improved, and the mechanical property of the silicon nitride ceramic material is further improved.
本发明涉及氮化硅陶瓷球技术领域，具体涉及一种高性能大尺寸氮化硅陶瓷球及其制备方法和应用。本发明提供了一种高性能大尺寸氮化硅陶瓷球，包括以下重量份数的制备原料：硅粉10～15份；氮化硅90～100份；所述氮化硅粉体中α相氮化硅的质量含量为95～99％；MgO 3～4份；CeO21～1.5份；Y2O30.5～1份；TiC 1份。本发明通过四组分烧结助剂复配，能够有效提高氮化硅陶瓷材料的致密程度，进而提升其力学性能。
