Electron Paramagnetic Resonance (EPR) in Boron Nitride, Boron and Boron Carbideumination gives some insight into the interaction between the spin-carrying centers (Sects. 3 and 4). EPR in boron carbide (Geist, 1964a) is similar to that in boron (Sect. 5); combined measurements of electrical conductivity, EPR intensity and Hall coefficient show some correlation between these pr

Crystal Chemistry of Higher Boridesographic sites leading to multiple stoichiometries within the same B. framework may also confuse the stoichiometries of these structures. In the light of these potential complications it becomes even more urgent that the crystal chemistry of the higher borides be expressed in a uniform and consisten

Such diverse applications of borides as in protective armor, nuclear reactors, coatings, reinforcement, etc. can hardly all be presented in sufficient detail by a single author. On the ot

The Electronic Structures of the Hexaborides and the Diboridesization of the stability of these materials as well as the metal-deficient and mixed-metal phases. Band structure and density-of-states calculations lead to values of electrical conductivities and Hall coefficients for these materials which agree well with experimental data.
