Abstract
A hot pressed intermetallic composite comprises titanium diboride and boron nitride and an effective amount of tungsten to reduce erosion of the composite and reduce the rate at which the electrical resistivity of the composite changes during its use.
Claims6
A hot pressed intermetallic composite comprised of titanium diboride and boron nitride and including tungsten in an amount of from about 0.1% to 20% by weight and having a density of at least 85% of theoretical.
A hot pressed intermetallic composite for use in the evaporation of aluminum comprising titanium diboride and boron nitride and an effective amount of tungsten to reduce erosion of said composite and reduce the rate at which the electrical resistivity of said composite changes during its use.
