Abstract
A method of forming tungsten tetraboride, by combining tungsten and boron in a molar ratio of from about 1:6 to about 1:12, respectively, and firing the combined tungsten and boron in the hexagonal boron nitride crucible at a temperature of from about 1600 C to about 2000C, to form tungsten tetraboride.
