Preparation process of reactive sintering silicon carbide ceramic granulation powder
The invention relates to the technical field of preparation of silicon carbide ceramic powder, and particularly discloses a preparation process of reactive sintering silicon carbide ceramic granulation powder, which comprises the following steps: step 1, preparing premixed liquid: dissolving an initial adhesive, a ceramic dry pressing adhesive, a lubricant, a pressing aid and a dispersing agent in deionized water, and stirring to uniformly mix the premixed liquid; according to the invention, by increasing the water absorption performance and adding the material, in the forming process of the silicon carbide ceramic powder, the friction force among particles is relatively small, the flowability among the powder is increased, the silicon carbide ceramic powder is uniformly formed, the energy consumption in the production process is reduced, and the production efficiency is improved; and in the sintering process, the uniformity of the pore structure of the silicon carbide ceramic powder in the sintering process is improved, and gas diffusion and substance transmission are facilitated, so that the sintering temperature is reduced, the sintering time is shortened, and the compactness and the mechanical property of the silicon carbide ceramic are improved.
本发明涉及碳化硅陶瓷粉料制备技术领域，具体公开了一种反应烧结碳化硅陶瓷造粒粉料的制备工艺，包括以下步骤：步骤一：配置预混液：将初粘剂、陶瓷干压粘接剂、润滑剂、助压剂、分散剂溶解于去离子水中，搅拌，使预混液混合均匀；本发明，通过增加吸水性能和添加增加材料的作用，使得碳化硅陶瓷粉料在成型过程中，颗粒之间的摩擦力较小，增加了粉料之间的流动性，使碳化硅陶瓷粉料成型呈均匀的现象，降低了生产过程中的能源消耗，提升了生产效率；且在烧结过程中，增加了碳化硅陶瓷粉料在烧结过程中孔隙结构的均匀性，利于气体的扩散和物质的传输，从而减少了烧结温度和烧结时间，提升了碳化硅陶瓷的致密性和机械性能。
