High-Pressure Metallic Indium Telluride: Preparation and Crystal Structure
Abstract:
The metallic high-pressure form of indium telluride may be prepared under high pressure at 150 degrees C and retained at ambient conditions without low-temperature quenching. It has the NaCl (type B1) structure with a cell edge of 6.160 +/- .005 A and a calculated density of 6.887 g/cm(2). The density increase relative to the low-pressure polymorph is 15.6 percent.

Metallic Solids
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability. Many...
