Superhard boron-rich borides and studies of the B C N system

The crystal chemistry of the B 4C-type structures is described. New structural data for B 12S, B 13Se and B 6O are presented. It is found that B 6O with a microhardness larger than that of B 4C invariably contains a high concentration of vacancies at the oxygen position (B 6O 1- x with x in the rang...

Zusammenfassung:	The crystal chemistry of the B 4C-type structures is described. New structural data for B 12S, B 13Se and B 6O are presented. It is found that B 6O with a microhardness larger than that of B 4C invariably contains a high concentration of vacancies at the oxygen position (B 6O 1- x with x in the range 0.76–0.84). Structural results for graphite-like phases in the B-C-N system are presented and discussed.
