Embodiment 1
[0042] In terms of parts by weight, weigh 30 parts of nano-silica powder and 12 parts of carbon powder respectively, add the carbon powder to the nano-silica powder, place it in a high-speed mixer, and stir and mix at 800r / min for 12 minutes at room temperature. To obtain mixed powder, put the mixed powder in a tubular atmosphere furnace, feed nitrogen gas at a rate of 120mL / min, raise the temperature to 1600°C at a rate of 20°C / min at room temperature, keep the temperature for calcination for 1~2h, and cool down with the furnace to At room temperature, calcined powder is obtained. Put the calcined powder in a muffle furnace, raise the temperature to 400°C at a rate of 5°C / min at room temperature, keep the temperature for calcination for 30 minutes, and cool down to room temperature with the furnace to obtain nano-silicon nitride powder; then press In terms of parts by weight, weigh 40 parts of nano-silicon nitride powder, 12 parts of hexamethyldisilazane, 8 to 10 parts of stea...
