摘要：
POROUS PELLETS CHARACTERIZED BY A MODERATELY REACTIVE CRUST AND A SOFTER CORE OF HIGHER REACTIVITY ARE PRODUCED BY FORMING AGGLOMERATES CONTAINING A METAL FLUORIDE POWDER AND A SELECTED AMOUNT OF WATER. THE METAL FLUORIDE IS SELECTED TO BE SINTERABLE AND ESSENTIALLY NON-REACTIVE WITH GASEOUS FLUORINATING AGENTS. THE AGGLOMERATES ARE CONTACTED WITH A GASEOUS FLUORINATING AGENT UNDER CONTROLLED CONDITIONS WHEREBY THE HEAT GENERATED BY LOCALIZED REACTION OF THE AGENT AND WATER IS LIMITED TO VALUES EFFECTING BONDING BY LOCALIZED SINTERING.
