Abstract

La présente invention décrit un matériau réfractaire dense qui comprend une matrice de spinelle et une phase d'initiation de micro-fissure dispersée dans la matrice. Le matériau d'initiation de la micro-fissure introduit des micro-fissures dans le matériau réfractaire ce qui inhibe toute défaillance catastrophique résultant des effets du choc thermique. L'invention concerne aussi un procédé de fabrication d'un matériau réfractaire dense qui comprend des étapes consistant à mélanger des oxydes précurseurs d'un matériau de spinelle, à calciner le matériau, à former le matériau de spinelle à l'état vert du produit et à cuire le matériau dans cet état pour obtenir le produit final.
