Title (EN) A METHOD OF PRODUCING A BODY COMPRISING POROUS ALPHA SILICON CARBIDE AND THE BODY PRODUCED BY THE METHOD
(FR) PROCÉDÉ DE PRODUCTION D'UN CORPS COMPRENANT DU CARBURE DE SILICIUM ALPHA POREUX ET CORPS PRODUIT SELON CE PROCÉDÉ
Abstract:
(EN) The present invention relates to a method of producing porous alpha-SiC containing shaped body comprising anhedral crystals in a concentration higher than 60%. and porous alpha-SiC containing shaped body produced by that method. The porous alpha-SiC containing shaped body shows a characteristic microstructure providing a high degree of mechanical stability. The product is used as diesel particulate filter and/or as catalyst support. A method of producing a porous silicon carbide product, said method comprising: - preparing a mixture comprising silicon, carbon, at least one silicide forming and carbide forming agent (e.g. Al, Zn or Mg) and at least one alloy forming agent (Cu)
(FR) La présente invention concerne un procédé de production de corps façonné contenant du SiC alpha poreux comprenant des cristaux xénomorphes dans une concentration supérieure à 60 %, et un corps façonné contenant du SiC alpha poreux produit selon ce procédé. Le corps façonné contenant du SiC alpha poreux présente une microstructure caractéristique assurant un niveau élevé de stabilité mécanique. Le produit est utilisé comme filtre à particules diesel et/ou comme support de catalyseur. L'invention concerne également un procédé de production d'un produit en carbure de silicium poreux, ledit procédé consistant à : préparer un mélange comprenant du silicium, du carbone, au moins un agent de formation de siliciure et de formation de carbure (par exemple, Al, Zn ou Mg) et au moins un agent de formation d'alliage (Cu).
