摘要:
Processes comprising: melting a mixture comprising a valve metal precursor and a diluting agent in at least one first vessel under a first set of temperature and residence time conditions; transferring the mixture to at least one second vessel; and initiating, in the at least one second vessel, a reaction of the valve metal precursor to form a valve metal under a second set of temperature and residence time conditions; valve metal powder prepared thereby and uses therefor.
