alpha -Al sub 2 O sub 3 -- beta -Si sub 3 N sub 4 whisker composite ceramics with a whisker content of 20 wt.% were prepared by hot-pressing at prescribed temperature between 1300-1800 deg C for 30 min under the pressure of 30 MPa. Fairly dense composites were obtained at sintering temperature >...
