A preparation method of a silicon carbide ceramic plugboard with a trapezoidal hexagonal prism structure is characterized by comprising the following steps: uniformly mixing silicon carbide powder, metal silicon powder and carbon powder according to a certain proportion, then preparing slurry, and splicing silicon carbide ceramic elements with the trapezoidal hexagonal prism structure into the ceramic plugboard according to a certain size. The method comprises the following steps of: splicing ceramic inserting plates, inserting dovetail-shaped cone silicon carbide ceramic elements or flat-top dovetail-shaped cone silicon carbide ceramic elements into gaps of the ceramic inserting plates, pouring the slurry into the gaps of the elements in the spliced ceramic inserting plates in an arc-shaped ceramic inserting plate blank mold, pressing, heating, curing, cooling and demolding to prepare a ceramic inserting plate blank, and sintering the ceramic plug board blank body into the ceramic plug board at a certain temperature in a buried sintering and siliconizing manner. According to the prepared ceramic plug board, the silicon carbide ceramic elements of the trapezoidal hexagonal prism structures are spliced in a crossed mode, longitudinal kinetic energy can be dispersed in the transverse direction to the maximum extent, joints are formed by firing materials of the same material as the trapezoidal hexagonal prism structures into a whole, and the bonding strength is high.
一种梯形六方柱结构碳化硅陶瓷插板的制备方法，其特征在于，将碳化硅粉、金属硅粉、碳粉按一定比例混合均匀，然后制成浆料，再将梯形六方柱结构碳化硅陶瓷元件按照一定尺寸拼接成陶瓷插板，并将燕尾形锥体碳化硅陶瓷元件或平顶燕尾形锥体碳化硅陶瓷元件插入上述陶瓷插板的间隙里，在弧形陶瓷插板坯体模具里将上述浆料灌注于拼接成的陶瓷插板中各元件的间隙里，并压制、加热、固化，待冷却脱模后制成陶瓷插板坯体，在一定温度下将陶瓷插板坯体埋烧渗硅烧制成陶瓷插板。本发明所制备的陶瓷插板是通过梯形六方柱结构碳化硅陶瓷元件交叉拼接，可使纵向动能最大程度向横向分散，且接缝是由与梯形六方柱同材质的材料烧制成一体，结合强度高。
