Preparation method of high-thermal-conductivity diamond-silicon carbide multiphase ceramic and heat dissipation substrate
The invention provides a preparation method of high-thermal-conductivity diamond-silicon carbide multiphase ceramic and a heat dissipation substrate. The preparation method comprises the following steps: mixing a first diamond, a second diamond, a third diamond and a binder solution, and carrying out molding and cold isostatic pressing treatment to obtain a green body; and then performing degreasing and siliconizing treatment to obtain diamond-silicon carbide multiphase ceramic, and preparing the diamond-silicon carbide multiphase ceramic into the heat dissipation substrate. According to the technical scheme, the content of diamond in a matrix is increased, and the content of free silicon is reduced, so that the comprehensive performance of the diamond-silicon carbide composite ceramic is improved.
本发明提供了一种高导热金刚石‑碳化硅复相陶瓷的制备方法及散热基板，包括将第一金刚石、第二金刚石、第三金刚石、粘结剂溶液混合、成型和冷等静压处理得到坯体，然后进行脱脂、渗硅处理得到金刚石‑碳化硅复相陶瓷并制成散热基板。本发明的技术方案提高了基体内金刚石含量和降低了游离硅含量，从而提高了金刚石‑碳化硅复相陶瓷的综合性能。
