Abstract
Silicon nitride nanoceramics and aluminum nitride nanoceramics are fabricated by pulsed electric current sintering. These nanoceramics could be densified without grain growth, because of high heating rate of the pulsed electric current sintering. A sintering additive is effective for lowering sintering temperature and aluminum nitride nanoceramic could be obtained as a result of 1wt% of Ca_3Al_2O_6 addition.
