Superconducting heat diamond ceramic-based composite material and preparation method thereof
The invention provides a super-heat-conduction diamond ceramic-based composite material and a preparation method thereof. The method comprises the following steps: firstly, selecting two diamonds with different particle sizes as raw materials; wherein the diamonds with large particle sizes are skeleton diamonds, the diamonds with small particle sizes are graded diamonds, and the ratio of the particle sizes of the graded diamonds to the skeleton diamonds is (1: 5)-(1: 15); then mixing two kinds of diamonds with different particle sizes with deionized water by a wet method to obtain a mixture; pouring the mixture into a graphite mold, and carrying out drying treatment to obtain a green body; and finally, the blank and the graphite mold are put into a vacuum furnace to be subjected to gas-phase siliconizing, and the composite material is obtained. According to the method disclosed by the invention, no additional carbon is introduced in the preparation process, so that the problems that additional carbon particles are difficult to mechanically disperse uniformly and additional resin carbon is difficult to crack uniformly are solved, the prepared composite material is more uniform, and the heat-conducting property of the obtained diamond ceramic-based composite material is higher.
本发明提供了一种超导热金刚石陶瓷基复合材料及其制备方法，该方法为：先选取两种不同粒度大小的金刚石为原料；其中，粒度大的金刚石为骨架金刚石，粒度小的金刚石为级配金刚石，级配金刚石和骨架金刚石的粒度大小之比为1:5～1:15；然后将两种不同粒度大小的金刚石与去离子水进行湿法混合，得到混合物；再将所述混合物倒入石墨模具中进行烘干处理，得到坯体；最后将所述坯体连同石墨模具放入真空炉进行气相渗硅，得到复合材料。本发明方法在制备过程中没有外加碳的引入，避免了外加碳颗粒难以机械分散均匀和外加树脂碳难以裂解均匀的问题，使得制备的复合材料更为均匀，得到的金刚石陶瓷基复合材料的导热性能更高。
