Abstract

This invention provides a bi-liquid phase sintering process for producing Al2O3super hard ceramic-metal utilizing cryolite and a binding alloy, which utilizes a formula of cryolite and Al0.5CoCrCuFeNi high entropy alloy, by ball milling and bi-liquid phase sintering process and the like, to obtain a highly compacted high entropy alloy binding Al2O3 super hard ceramic metal; wherein the bi-liquid phase contains cryolite and Al2O3, the cryolite in liquid phase may dissolve Al2O3 therefore having good wetability with Al2O3, furthermore the remaining Al after Na and F impurities being vaporized may combine with Al0.5CoCrCuFeNi high entropy alloy to form a part of the high entropy alloy. By means of the well wetability property of bi-liquid phase sintering, Al.sub.2O.sub.3 and Al0.5CoCrCuFeNi high entropy alloy may be compactly sintered into a good complex material.
