Pressed insulating composite moulding

摘要

In the case of a pressed insulating composite moulding of powdered ceramic material, comprising at least two ceramic material layers which differ in their structure, for the purpose of better adhesion, a layer (3) of a first material is enclosed, at least on two sides, by two layers (2a, 2b) of a second material, and the enclosing layers (2a, 2b) are interconnected by means of webs (2c) penetrating the middle layer (3) and interlocked therewith. The said webs bond particularly intimately with the outer layers, since they likewise consist of the second material. <IMAGE>
