Abstract

L'invention porte sur un procédé de préparation de composites de nitrure d'aluminium et de carbure de silicium, consistant à porter du carbure d'aluminium et du nitrure de silicium et/ou du silicium à l'aide d'azote, à une température d'au moins 1400 °C en présence d'un ou plusieurs coréactants et éventuellement de substances liées ensemble par le produit de réaction à un composite. Les composites de nitrure d'aluminium et de carbure de silicium sont produits par la mise en réaction de carbure d'aluminium (Al4C3) avec du nitrure de silicium (Si3N4) ou du silicium (Si), dans une atmosphère d'azote. Les adjuvants de frittage et les oxydes contaminants tels que le SiO2 et l'Al2O3 réagissent avec l'Al4C3 et l'azote pour donner rspectivement du SiC et de l'AlN.
