Abstract
Fremgangsmåte for fremstilling av aluminiumnitrid/silisiumkarbid-kompositter, ved at aluminiumkarbid og silisium- nitrid og/eller silisium oppvarmes til reaksjon sammen med nitrogen til en temperatur på minst 1400* C i nærvær av en eller flere medreaktanter og eventuelt stoffer som bindes sammen av reaksjons- produktet til en kompositt. Det fremstilles kompositter av aluminiumnitrid og silisiumkarbid ved at aluminiumkarbid (A14C3) omsettes med silisiumnitrid (Si3N4) eller silisium (Si). Reaksjonene gjennomføres i en rii- trogenatmosfære. Oksydiske forurensnin- ger og sintringshjelpemidler, så som SiO2 og A12O3 reagerer med A14C3 og ni- trogen under dannelse av SiC, hhv. A1N.Process for the preparation of aluminum nitride / silicon carbide composites by heating aluminum carbide and silicon nitride and / or silicon in reaction with nitrogen to a temperature of at least 1400 ° C in the presence of one or more co-reactants and optionally substances which are bound together by reaction - the product of a composite. Composites of aluminum nitride and silicon carbide are prepared by reacting aluminum carbide (A14C3) with silicon nitride (Si3N4) or silicon (Si). The reactions are carried out in a nitrogen atmosphere. Oxidic contaminants and sintering aids such as SiO2 and A12O3 react with A14C3 and the nitrogen to form SiC, respectively. A1N.
