Abstract:
1. A process for manufacturing a powder comprising an element M, an element A, and an element X, in the respective proportions (n+1±ε 1 ), 1±ε 2 and n±ε 3 , wherein: A is selected from the group consisting of Cd, Al, Ga, In, Tl, Si, Ge, Sn, Pb, P, As, and S; M is a transition metal; X is selected from the group consisting of B, C, and N; n is an integer equal to 1, 2, or 3; and ε said powder having a mean particle size ranging from 10 to 200 nm, comprising: a) mixing together, with no heating and in the absence of oxygen, a precursor of M, a precursor of A and a precursor of X to obtain a mixture, said precursors being in the form of a gas, a solid in suspension in a gas, and/or a liquid in suspension in a gas; and b) heating said mixture obtained in step a) to a temperature effective for forming the powder.
