PT-Keramik® is an innovative product that combines the advantages of the paper-making procedure with the positive properties of ceramic materials. There always have been ceramic raw materials like kaolin or titanium oxide within the paper manufacture. If these substances are, for example, replaced by aluminua and its content is increased to a maximum, it becomes a preceramic paper. This can be prepared and processed on industrial paper machines in a larger scale. Thus, it is possible to produce very stiff light weight structures by using the corrugated-paper technology. The paper-components such as cellulose and additives are removed thermally and a pure alumina ceramic stays back after the final sintering process. The known techniques for the manufacture of paper are used for the production of these ceramics, that is why these are called “the paper-technologially produced ceramics” (PT-Keramik®). This technology is currently unique for ceramics and is offered exclusively by the WZR ceramic solutions GmbH.
PT-Keramik® in the form of a corrugated board (called corrugated ceramic) are high temperature resistant and have, due to their wave structure, a high strength and stiffness and a very low heat capacity. One of the applications are firing auxiliaries or such called kiln furnitures for the sintering-process of ceramic or metallic components. Those have to be stacked in the klins, instead of the massive ceramic boards used right now. Within the Sintering of the technical-ceramics it is possible to reduce the mass of the kiln furniture up to 60% by using kiln furniture made of Al2O3. As a result, energy savings of at least 40% are possible. The current standard product is a corrugated alumina-based ceramic with maximum dimensions of 300x300mm. The load capacity can be customized by laminating several corrugated papers on each other. We are able to develop user specific solutions based on other raw materials as well. The variety of the papermaking-process offers almost unlimited possibilities for new geometries; we are constantly aggrandizing our array of products and geometries.
