利用还原烧结法成功地制得Ａｌ２Ｏ３／金属复合材料。采用微细α－Ａｌ２Ｏ３（平均粒径０．２μｍ）与Ｗ金属粉（粒径０．６μｍ）混合物经烧结制取Ａｌ２Ｏ３／Ｗ复合材料时，为了获得分散的微细金属可采用ＷＯ３（平均粒径７０μｍ）相当于α－Ａｌ２Ｏ３粉末体积的２．５
The Al2O3 / metal composites were successfully prepared by reduction sintering. When an Al2O3 / W composite material is produced by sintering a mixture of fine α-Al2O3 (average particle diameter of 0.2 μm) and W metal powder (particle diameter of 0.6 μm), WO3 (average particle diameter of 70 μm ) Corresponds to 2.5 of the volume of α-Al 2 O 3 powder
