Process for making a reaction-sintered carbide-based composite body with controlled combustion synthesis

摘要

There is disclosed a process for preparing a sintered ceramic composite which is comprised of alumina and metal carbide. In the first step of this process, a mixture of silica, aluminum material, and carbon is comminuted until a substantially single-phase material is produced. In the second step of the process, the single phase material is granulated and formed into a green body. Thereafter, the green body is preferably packed in inert powder, placed into a closed reactor, and ignited.
