| Research Abstract |
The reactive infiltration of molten aluminum into a powder preform was investigated as a processing route for aluminum nitride (AlN). As the powder preform, titanium and boron nitride (BN) powders were blended and compacted. The infiltration occurred spontaneously at temperatures above 1173 K, and turned out to be irrelevant to the BN powder size and BN/Ti blending ratio. However, the conversion ratio of BN to AlN was prominent above 1673K. When the amount of aluminum is not sufficient, residual BN was observed in the microstructure, and the morphology of the mold was not copied precisely. The specimen containing rich aluminum showed the good transcriptional behavior.
