Abstract

L'invention a trait à un procédé de fabrication de pièces moulées réfractaires. Elle a pour objet un procédé de fabrication d'une pièce moulée réfractaire, liée au phosphate, résistant à des températures supérieures à 1300 degrés C selon lequel une charge réfractaire et du Al(H2 PO4 ) 3 .xH2 O ou un polyphosphate comme liant sont appliquées sur un substrat à une ou plusieurs couches et sont ensuite durcies pour former une structure à paroi mince, à une ou plusieurs couches. Application : accessoires de coulée de métaux ou composants électrotechniques.
