A process for removing binder from a body comprising ceramic particles and binder by heating the body at a substantially constant rate of temperature rise over the temperature range where a peak rate of body weight loss occurs in a gaseous environment of inert gas and oxidizer wherein the oxidizer concentration varies with the rate of temperature rise to reduce the peak rate of body weight loss.
Procédé pour enlever un liant d'un corps comportant des particules de céramique et un liant en chauffant le corps à un taux de montée en température essentiellement constant au-dessus de la plage de température à l'intérieur de laquelle on obtient un taux maximal de perte de poids corporel dans un milieu gazeux composé de gaz inerte et de comburant. La concentration de comburant varie au même rythme que la montée en température afin de réduire le taux maximal de perte de poids corporel.
