Step 4, containing Ti3SiC2The preparation of the low-density carbon/carbon compound material of ceramic powder
Using propylene or natural gas as reacting gas, contain Ti prepared by step 33SiC2Sink in the prefabricated carbon fiber body of ceramic powder Product pyrolytic carbon, prepares density and contains Ti for 1.2~1.6g/cm33SiC2The carbon/carbon compound material of ceramic powder；
Step 5, high-temperature process
Carbon/carbon compound material prepared by step 4 is subjected to high-temperature process under nitrogen or argon gas atmosphere, what is be heat-treated contains Ti3SiC2The carbon/carbon compound material of ceramic powder；
Step 6：Siliconising is handled
Contain Ti after heat treatment prepared by step 53SiC2The carbon/carbon compound material of ceramic powder is carried out at siliconising in a vacuum furnace Reason, keeps the temperature after continuing heating；Cool to room temperature after insulation with the furnace, obtain Ti3SiC2The equally distributed carbon pottery brake of ceramic powder Material.
