Silicon carbide ceramic sealing ring and preparation method thereof
The invention relates to a preparation method of a silicon carbide ceramic sealing ring, which is characterized by at least comprising one or more of the following steps of by using silicon carbide asa main raw material, introducing one or more of a first sintering aid, a second sintering aid, a water reducing agent and other aids according to a preset mass ratio, carrying out pulverization mixing, and granulating and sintering the premixed slurry obtained after mixingto obtain the silicon carbide ceramic sealing ring. The premixed slurry comprises first premixed slurry and second premixed slurry which are obtained in the mode that silicon carbide and a second sintering aid are powdered and mixed with a first sintering aid and/or the water reducing agent which are/is added at least twicerespectively.
本发明涉及一种碳化硅陶瓷密封环的制备方法，其特征是，所述制备方法至少包括以下步骤中的一个或几个：以碳化硅为主要原料，按照预设质量比例引入第一烧结助剂、第二烧结助剂、减水剂和其他助剂中的一个或几个进行粉末化混合，混合后得到的预混浆料经造粒烧结制得碳化硅陶瓷密封环，其中，所述预混浆料包括通过将碳化硅和第二烧结助剂分别与至少分两次加入的第一烧结助剂和/或所述减水剂进行粉末化混合的方式所得到的第一预混浆料和第二预混浆料。
