Silicon carbide ceramic product and preparation method thereof
A silicon carbide ceramic product and a preparation method thereof belong to the field of materials. The preparation method of the silicon carbide ceramic product comprises the following steps: molding the mixed silicon carbide ceramic raw materials containing the binder to obtain a green body; carrying out heat treatment on the green body to remove the binder, and cooling to obtain a silicon carbide ceramic porous matrix; and embedding the silicon carbide ceramic porous matrix in the embedding powder, pre-pressing, and sintering at the sintering temperature of 1700-2100 DEG C in an inert atmosphere to obtain the silicon carbide ceramic product. The preparation method is simple to operate and low in cost, not only can obtain a compact silicon carbide ceramic product, but also can effectively improve the compactness of the silicon carbide ceramic product on the basis of not increasing the sintering temperature compared with hot-pressed sintering and pressureless sintering of silicon carbide; and compared with a hot isostatic pressing technology, the method can improve the density without an additional special mold, the production cost is effectively reduced, and the method is suitable for industrial production.
一种碳化硅陶瓷制品及其制备方法，属于材料领域。碳化硅陶瓷制品的制备方法包括：将混合后的含有粘结剂的碳化硅陶瓷原料制作成型，获得生坯。将生坯热处理以去除粘结剂，冷却，获得碳化硅陶瓷多孔基体。将碳化硅陶瓷多孔基体包埋于包埋粉料中并预压后在惰性气氛中，在1700℃～2100℃的烧结温度下烧结，获得碳化硅陶瓷制品。上述制备方法操作简单且成本低，不仅能够获得致密的碳化硅陶瓷制品，同时相比于热压烧结和无压烧结碳化硅的方式，能够在不增加烧结温度的基础上有效提高其致密度，相比于热等静压技术，在不需要额外的特制的模具即可提高其致密度，有效降低生产成本，适于工业化生产。
