Abstract

A ceramic material is identified having particular utility as a thermal barrier or thermal insulating coating exhibiting anti-corrosion properties. The ceramic materials comprise alumina garnet structures involving addition of a lanthanide or transition metal being accompanied by a doping agent in the form of molybdenum. Specifically, Mo doped YAG and Mo doped YbAG are provided exhibiting significantly reduced calcinating temperatures required for garnet structure crystallisation. A synthetic route is also provided involving sol-gel techniques utilising of metal inorganic and organic precursors.
