Abstract
A pressable powder is formed by a method comprising [I] mixing, in essentially deoxygenated water, [A] a first powder selected from the group consisting of a transition metal carbide and transition metal with [B] an additional component selected from the group consisting of (i) a second powder comprised of a transition metal carbide, transition metal or mixture thereof; (ii) an organic binder and (iii) combination thereof and [II] drying the mixed mixture to form the pressable powder, wherein the second powder is chemically different than the first powder. The pressable powder may then be formed into a shaped part and subsequently densified into a densified part, such as a cemented tungsten carbide.
