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 (v
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+1A zXn. 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.

What is claimed is: 1. A method of producing a single-phase composition Mn+ 1AzXn, by means of SHS (Self-propagating High Temperature Synthesis), where n lies within a range of 0.8-3.2, where z lies within a range of 0.8-1.2, where component M is at least one metal selected from the group consistin
What is claimed is: 1. A method of producing a single-phase composition Mn+ 1AzXn, by means of SHS (Self-propagating High Temperature Synthesis), where n lies within a range of 0.8-3.2, where z lies within a range of 0.8-1.2, where component M is at least one metal selected from the group consisting of Ti (titanium), Sc (scandium), V (vanadium), Cr (chromium), Zr (zirconium) , Nb (niobium) and Ta (tantalum) , and where component X is at least one of the non-metals C (carbon) and N (nitrogen), and where component A is at least one of the chemical elements Si (silicon), Al (aluminum), and Sn (tin) or a compound containing at least one of said chemical elements, such that a final, desired compound will include the components Mn+1AzX n, said method comprising the steps of: forming a powder mixture from components M, X, and A; adding to the powder mixture a pre-reacted compound to provide a resulting mixture, the pre-reacted compound having the composition Mn+1AzX n and serving as a heat sink; reacting the resulting mixture by igniting said powder mixture under an inert atmosphere to prevent dissociation of a resulting single-phase composition; and maintaining the reaction temperature at or above a temperature at which the components react but below a temperature at which the resulting single-phase composition dissociates. 2. A method according to claim 1, wherein n ranges from 1 to 3. 3. A method according to claim 1, wherein the single-phase material is Ti3SiC2. 4. A method according to claim 1, wherein the single-phase material is at least one of Ti2AlC and Ti2SnC. 5. A method according to claim 1, wherein the pre-reacted material is present at about 25 weight-% of the mixed materials. 6. A method according to claim 5, wherein the pre-reacted material is Ti3SiC2. 7. A method according to claim 1, wherein the inert atmosphere has a partial pressure of oxygen sufficiently low to prevent dissociation of the single-phase composition.
