摘要

The cutting tool in which the alumina and the oxide of the present invention were sintered with silicon nitride by discharge plasma sintering was composed of ₂ wt% of mixed powder of alumina (Al ₂ O ₃ ) powder and oxidized emulsion (Er ₂ O ₃ ) in 98 wt% (Eutectic) reaction which simultaneously deposits silicon nitride and alumina (Al ₂ O ₃ ) and oxidized air (Er ₂ O ₃ ) components during sintering is performed at a temperature of 1700 to 1800 ° C .
