High-thermal-conductivity silicon carbide material and preparation method thereof
The invention relates to the field of mechanical sealing element materials, and particularly discloses a high-thermal-conductivity silicon carbide material and a preparation method thereof. The high-thermal-conductivity silicon carbide material consists of the following raw materials in parts by weight: 65-75 parts of silicon carbide, 3-10 parts of diamond, 18-22 parts of graphite powder, 1-5 parts of a binder, 2-10 parts of a sintering aid, 1-3 parts of boron powder and 5-15 parts of a silicon wafer. The preparation method comprises the following steps: S1, weighing the raw materials according to the formula proportion, adding water, and uniformly mixing to obtain slurry; s2, carrying out spray drying granulation on the slurry obtained in the step S1 to obtain particles; s3, carrying out compression molding on the particles in the S2 to obtain a biscuit; s4, baking and forming the biscuit in the S3, and then processing; and S5, performing vacuum sintering, and naturally cooling to obtain the high-thermal-conductivity silicon carbide material. The high-thermal-conductivity silicon carbide material can be used for preparing mechanical sealing rings and has good thermal conductivity.
