process for the production of a ceramic verbundkoerpern matrixmaterial, reinforced by zirconium oxide particles and, possibly, monokristalline silicon carbide fibers, as well as body obtained by this method.

摘要

The process comprises the following successive stages: 1) preparation of a homogeneous suspension of a mixture of a powder of the ceramic substance such as alumina, a doped or undoped zirconia powder and optionally monocrystalline SiC fibres in an aqueous medium containing at least one anionic deflocculating agent, 2) casting the suspension in a porous mould, 3) demoulding the raw article thus obtained, 4) drying the raw article, and 5) sintering the dried article, preferably under pressure.
