A preparation method of a ceramic plugboard with longitudinally distributed silicon carbide whiskers is characterized in that silicon carbide whisker powder is longitudinally distributed on a retainer plate through a whisker longitudinal distribution device to form a silicon carbide whisker powder layer with a certain thickness, then silicon carbide micro powder, metal silicon powder and carbon micro powder are prepared into slurry with a certain viscosity, and the silicon carbide whisker powder layer is prepared into a ceramic plugboard with longitudinally distributed silicon carbide whiskers. And uniformly spraying the slurry on a silicon carbide whisker powder layer, pressing into a plate after uniformly wetting, shaping into an arc shape to prepare a ceramic insertion plate blank with longitudinally distributed silicon carbide whiskers, and burying, sintering and siliconizing at a certain temperature to prepare the ceramic insertion plate with longitudinally distributed silicon carbide whiskers. According to the prepared ceramic plugboard, the silicon carbide whiskers are longitudinally arranged, so that the bending strength of the silicon carbide ceramic plugboard is remarkably improved, longitudinal kinetic energy can be dispersed to the transverse direction to the greatest extent, and the breakdown resistance of the silicon carbide whisker ceramic plugboard is improved.
一种碳化硅晶须纵向分布的陶瓷插板的制备方法，其特征在于，将碳化硅晶须粉体通过晶须纵向布料装置按纵向分布在托料板上形成一定厚度的碳化硅晶须粉体层，再将碳化硅微粉、金属硅粉、碳微粉制成一定粘度的浆料，将该浆料均匀喷洒在碳化硅晶须粉层上，待均匀润湿后压制成板，经整形成弧型后，制成碳化硅晶须纵向分布的陶瓷插板坯体，在一定温度下埋烧渗硅制成碳化硅晶须纵向分布的陶瓷插板。本发明所制备的陶瓷插板是通过碳化硅晶须纵向排列，显著提高了碳化硅陶瓷插板的抗弯强度，可使纵向动能最大程度向横向分散，提高了碳化硅晶须陶瓷插板的抗击穿能力。
