Abstract
A method is described for sintering of highly loaded (less than or equ al to 20 vol%) alumina matrix/silicon carbide whisker or platelet comp osites to closed porosity. The method uses controlled heterogeneous pr ecipitation in a suspension of whiskers or platelets. The suspension-c oated particles are calcined to produce a free-flowing composite powde r which can be hot-pressed or free-sintered to high density. The resul ts of consolidation and mechanical property testing are reported.
