Material Basics

What means „Keramikblech“/„sheet ceramic“
“Keramikblech” is an oxide/oxide ceramic matrix com­posite. The standard ma­ter­ials were developed by the com­pany Walter E.C. Pritzkow Spezialkeramik. Since 2001 in close cooperation with Fraunhofer Institut für Silicat­forschung improved oxide / oxide ceramic matrix com­po­sites based on the fiber 3M™ Nextel™ 610 were devel­oped.

All this oxide/oxide ceramic matrix com­po­sites based on fabrics with con­tinuous ceramic fibers in the system Al2O3-SiO2 and matrix mate­rials in the system Al2O3-SiO2-ZrO2.

With these ma­te­rials we want to satisfy our users who are searching for mate­rials with the positive charac­teris­tics of metals like damage tol­erance and thermal shock re­sist­ance and the positive charac­teris­tics of ceramic like tem­per­a­ture resist­ance and corrosion resis­tance.
