Room-Temperature Deintercalation and Self-Extrusion of Ga from Cr2GaN

M. W. Barsoum, * L. Farber

Bulk samples of the layered ternary nitride Cr2GaN were observed to extrude filaments of pure elemental gallium at room temperature. This self-extrusion phenomenon is best described as a room-temperature deintercalation of gallium from the basal planes of porous Cr2GaN samples. The extruded filaments are single crystals with 2- to 100-micrometer diameters and can be several centimeters long.
