,Simple Rhombohedral Boron—Preparation and Properties,mple 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.

Remarks on Structure and Polymorphism in Boron,. Half of the atoms in alpha-rhombohedral boron, the polymorph formed at lowest temperatures, are used in delta linkages between icosahedra, and the structure then satisfies the electron counting set by the essentially molecular Longuet-Higgins and Roberts bonding theory. More conventional and appar

Preparation of Crystalline Boron, (2) upgrading the Moissan boron to 95% B by heating with fluorides, and (3) heating the upgraded boron by radiation in a vacuum. The latter step is accomplished by cold-pressing the powder into rings, stacking the rings to form a hollow cylinder, and heating in excess of 2000°C by means of a resist
