Embodiment 1
[0037] A new type of Hf x Zr 1-x C The preparation method of ceramic solid solution nanowire, this preparation method comprises the following steps:
[0038] Step S1: Grind and polish the C / C composite material matrix with a size of (8mm*8mm*2mm), ultrasonically clean it for 10-30 minutes, and put it in an oven to dry for later use;
[0039] Step S2: Ni(NO 3 ) 2 Configured as a solution with a concentration of 0.5mol / L;
[0040] Step S3: Put the prepared C / C composite material into the Ni(NO 3 ) 2 Soak in the solution for 8 hours, then dry in an oven at 80°C for 4 hours to obtain the initial sample;
[0041] Step S4: Preparation of Hf by LPCVD x Zr 1-x The specific method of C nanowire is as follows:
[0042] Step S41: Hang and place the first sample dried in step S3 in a tubular chemical vapor deposition furnace, and weigh HfCl according to a molar ratio of 3:7 4 and ZrCl 4 Powder, placed in a volatilization container;
[0043] Step S42: Use a vacuum pump to pump ...
