Outline of Final Research Achievements |
Titanium powder was put in an alumina crucible and covered with mixtures of iron, graphite and alumina powders. The crucible was set in an electric furnace, and then heated in the vicinity of 1273 K in the air. After heat treatment, the titanium powder became dark gray in color and titanium carbonitride, Ti(C, N), was formed on the titanium surface. This indicates that carbon in the powder mixture and nitrogen in the air were diffused into titanium by generating a non-oxidizing atmosphere in the crucible during heating. This unique heat treatment method was also applicable to the thermal reduction of titanium dioxide (rutile) powder.
