ABSTRACT:
Fully dense ceramic articles are prepared by mixing powders of silicon nide, aluminum oxide and magnesium oxide to form a composite powder composition wherein the magnesium oxide acts as a sintering aid, forming the composite powder into a desired shape, and heating the shaped composite powder composition in the absence of applied pressure at a temperature sufficient to effect sintering of the composition.
