ChemInform Abstract: Ti2GaC, Ti4GaC3and Cr2GaC - Synthesis, Crystal Growth and Structure Analysis of Ga-Containing MAX-Phases Mn+1GaCnwith M: Ti, Cr and n = 1, 3.

Abstract

Single crystals of Ga-containing MAX-phases Ti{sub 2}GaC, Ti{sub 4}GaC{sub 3}, and Cr{sub 2}GaC were grown from a metallic melt generated by an excess of Ga. This technique allows the crystal growth at different temperatures to control the product distribution. Compounds developed were Ti{sub 2}GaC and TiC at 1500 deg. C, and Ti{sub 2}GaC and Ti{sub 4}GaC{sub 3} at 1300 deg. C. Crystal structures were refined from single crystal data. Ti{sub 2}GaC and Cr{sub 2}GaC were previously known, and belong to the Cr{sub 2}AlC type as well as the solid solutions V{sub 2}Ga{sub 1-x}Al{sub x}C and Cr{sub 2}Ga{sub 1-x}Al{sub x}C. Ti{sub 4}GaC{sub 3} is one of the few 413-phases (P6{sub 3}/mmc, a=3.0690(4) A, c=23.440(5) A) and the first Ga-containing representative. The crystal structures of MAX-phases are intergrowths of layers of an intermetallic MGa in a hexagonal stacking sequence with carbidic layers (MC){sub n} of the NaCl type. The thickness of the layer depends from the value of n. The results of the structure refinements also demonstrate that also the structural details follow this description. - Graphical abstract: Single crystals of Ga-containing MAX-Phases (TiC){sub n}(TiGa) (n=1, 3) were grown from a metallic melt including and characterised by X-ray diffraction.
