| Abstract: | Ultra-fine powder of aluminum nitride were produced by evaporation of micron aluminum powder at nitrogen thermal plasma.The experimental result shows,the aluminum powder completely translated into aluminum nitride at the conditions as follows.Power:12kW;Operation gas:N 2,2m 3/h;Refrigerant gas:NH 3,0.6m 3/h;Carried gas:N 2,0.8m 3/h.Size range of aluminum nitride particle was measured to be from 40nm to 140nm,average size is 100nm .It was measured by scanning electric mirror(SEM) and particle size analyzer. |
