Abstract: The present invention relates to a material for use at temperatures exceeding 1200° C. and in oxidizing atmospheres consisting generally of an alloy between a metal, aluminium (Al) and carbon (C) or nitrogen (N). The invention is characterized in that the alloy has a composition MZAlYXW where M essentially consists of titanium (Ti), chromium (Cr) and/or niobium (Nb) and where X is carbon (C) or where X is nitrogen (N) and/or carbon (C) when M is titanium (Ti); and in that z lies in the range of 1.8 to 2.2, y lies in the range of 0.8-1.2 and w lies in the range 0.8-1.2, and wherein a protective oxide layer of Al2O3 is formed after heating to the mentioned temperature.

Abstract: A method of producing a single-phase composition Mn+1AzXn, primarily the production of the single-phase material Ti3SiC2, where n lies within a range of 0.8-3.2, where z lies within a range of 0.8-1.2, where M is at least one metal taken from the group of metals Ti (titanium), Sc (scandium), V (vanadium), Cr (chromium), Zr (zirconium), Nb (niobium) and Ta (tantalum), where X is at least one of the non-metals C (carbon) and N nitrogen), and where A is at least one of the chemical elements Si (silicon), Al (aluminum) and Sn (tin) or a compound of those elements, such that the final, desired compound will include the components Mn+1AzXn. A powder mixture of the components is formed and is ignited under an inert atmosphere to prevent promotion of dissociation and to cause the components to react.
