Abstract
A mixed oxide ceramic product is made directly from a metal alloy of titanium, zirconium and/or hafnium and niobium, tantalum or hafnium, where the normally combustible alloy of titanium and zirconium or hafnium is passivated by the addition of more than about 7 atomic percent of niobium and/or tantalum and or vanadium which alloy can then be heated in air at atmospheric pressure to a temperature of from about 800 degrees C. to about 1500 degrees C. to produce an adherent monolithic ceramic containing product.
