PREPARATION OF METAL DIBORIDE AND BORON-DOPED POWDERS

Abstract:

A method for producing a metal boride powder includes producing a boriding gas stream from a first powder in a first fluidizing bed reactor, delivering the boriding gas stream to a second fluidized bed reactor through a conduit fluidly connecting the first and second fluidized bed reactors, fluidizing a second powder in the second fluidized bed reactor, mixing the second powder with the boriding gas stream such that a metal boride or boron-doped powder is formed.
