| Abstract: | RF thermal plasma had been employed to prepare ZrB2 and ZrC ultra-fine powder materials based on thermodynamic calculation.The products were characterized by XRD,FESEM,and Hall flowmeter.Results revealed that high-purity ZrB2 and ZrC powders with an average diameter less than 100 nm could be obtained,and the apparent density of ZrB2 and ZrC was 0.71 g/mL and 0.46 g/mL.The production capability in the laboratory can reach 500 g/h. |
