Polymer-ceramic composite prodn.

摘要

A polymer-ceramic composite (I) is obtd. from a mixt. which has been precompacted to facilitate solid-state reactions and then bonded by material conversion of ceramic-formers below the sintering temp., with the aid of conventional auxiliary substances and ceramic moulding processes. The mixt. contains (a) inorganic ceramic-formers contg. or coated with functional gps., pref. OH gps., and (b) organosilicon cpds., both as reactive components accounting for most of the material. Also claimed is a process for the prodn. of (I) in which the material conversion is carried out at below 800 deg C.
