PROCESS FOR THE PREPARING VIA THE IN SITU REDUCTION OF THEIR COMPONENTS AND GRINDING OXIDE/METAL COMPOSITE MATERIALS |
摘要 |
A process for the preparation of composite materials consisting essentially of an oxide phase and a metal phase is effected by grinding a mixture of at least one oxide precursor of the metal phase of the composite with at least one reducing agent, the reducing agent being a precursor of the oxide phase. The grinding being performed in a high energy mechanical grinder for a sufficient length of time so that at least 80 percent of the oxide precursor is reduced to metal or to a metal alloy. The process is particularly valuable for the preparation of oxide/metal composite materials which have improved mechanical, electrical or radiation absorption properties.
