Preparation method of ceramic preform
The invention discloses a preparation method of a ceramic preform, and belongs to the technical field of ceramics. The preparation method of the ceramic preform comprises the following steps: putting a first raw material containing ceramic particles and a binder is put into a first preform mold with a first evanescent mode, and performing pre-pressing molding, wherein the first evanescent mode protrudes out of the inner surface of the first preform mold; and after the pre-pressing molding, carrying out first sintering molding, and softening the first lost foam or changing the first lost foam from a solid state to a liquid state or a gas state, so as to obtain the first ceramic preform. According to the method, the porosity of the ceramic preform can be adjusted, and demolding can be facilitated.
一种陶瓷预制体的制备方法，属于陶瓷技术领域。陶瓷预制体的制备方法，包括：将含有陶瓷颗粒和粘结剂的第一原料放入具有第一消失模的第一预制体模具中预压成型，其中，第一消失模凸出于所述第一预制体模具的内表面。预压成型后进行第一次烧结成型并将第一消失模软化或者将第一消失模从固态变成液态或气态，以得到第一陶瓷预制体。该方法能够调节陶瓷预制体的孔隙率，能够方便脱模。
