ALUMINUM NITRIDE, ALUMINUM NITRIDE CONTAINING SOLID SOLUTIONS AND ALUMINUM NITRIDE COMPOUNDS PREPARED BY COMBUSTION SYNTHESIS.

摘要

ALUMINUM NITRIDE POWDER, ALUMINUM NITRIDE SHEETS, SOLID SOLUTIONS IN ALUMINUM NITRIDE POWDER AND AT LEAST ANOTHER CERAMIC MATERIAL SUCH AS SILICON CARBIDE AND A BORIDE OF NUMBER OF ALUMINUM CARBIDE AND BORIDE AND BORURES. SYNTHESIS BY COMBUSTION AT LOW PRESSURES OF GASEOUS NITROGEN. POROUS BODIES OF ALUMINUM NITRIDE OR COMPOUNDS OF ALUMINUM NITRIDE OR BORIDES OR CARBIDE OF TRANSITION METALS ARE ALSO PREPARED BY A COMBUSTION SYNTHESIS AT THESE PRESSURES. POROUS BODIES ARE SUITABLE FOR INFILTRATION, WELL AS THEY FORM OR AFTER BEING COATED WITH AT LEAST ONE LAYER OF SILICATE MATERIAL, BY POLYMER OR METALS.
