Simple Rhombohedral Boron—Preparation and Properties

  • F. H. Horn


An allotrope of boron in a simple rhombohedral crystal structure has been reported [1,2]. Salient features of boron in this structure are reviewed. Simple rhombohedral boron has been crystallized from platinum melts. The necessary conditions are indicated. Some preliminary electrical and optical results for boron in the simple rhombohedral form are discussed and compared with results for boron that has been melted.
