Abstract

Ceramic sintering process to produce dense sintered bodies of compositions containing uranium oxide, characterized by comprising the steps of sintering bodies, made compact, of powders containing uranium oxide, at an alkanoe temperature of around 900 to 1500ºC, in a sintering atmosphere, comprising a mixture of carbon dioxide and hydrogen, and cooling the sintered body in an atmosphere, separated from the group consisting of dry hydrogen, wet hydrogen and a mixture of hydrogen and carbon dioxide.
