Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- The crystal chemistry of the B4C-type structures is described. New structural data for B12S, B13Se and B6O are presented. It is found that B6O with a microhardness larger than that of B4C invariably contains a high concentration of vacancies at the oxyge
