摘要
the present invention relates to the preparation of composite materials based on corundum and mullite. these materials have a wide industrial use, refractories, abrasives, etc.). these materials are made from local clay selected from hydrated high alumina (diaspore).the temperature is between and 12s0u00b0c flame with a heating rate of 10 c / min and another three hours. the materials developed are very interesting properties are values vary between 60 and 70 mpa, depending on the degree of enrichment in diaspore.these materials are good candidates for use as an abrasive in the field of surface treatment and as a refractory insulation.
