CERAMIC MATERIAL, METHOD FOR THE PRODUCTION THEREOF, USE OF THE CERAMIC MATERIAL, AND A LAYER OF THE CERAMIC MATERIAL ON A METALLIC OR CERAMIC BODY

摘要

Disclosed is a ceramic material which is suitable for coating a body by way of a thermal spraying method and which has a coefficient of longitudinal thermal expansion that may be matched to that of a metal. The ceramic material includes 10 to 95% by weight of MgAl2O4, 5 to 90% by weight of MgO, up to 20% by weight of Al2O3, remainder standard impurities, and has grains of MgO which are embedded in a matrix of MgAl2O4.
