Thermoresistant composite cordierite ceramics

A porous heat-resistant composite material has been developed from natural powders, which form a cordierite matrix during sintering, and a filler - a fibrous nanostructured aluminum oxide powder with high porosity and reactivity. It was found that the introduction of a nanocrystalline filler of aluminum oxide into a composite with a cordierite matrix causes the formation of a polyporous structure that increases porosity and heat resistance, as well as improves the thermal insulation properties of the material.
