Up to 3.3 wt% nitrogen can be incorporated into Na 2 O‐B 2 O 3 glass melts. The melting procedure is described, and structure models are given. In contrast to N‐containing silicate glasses, the borate glasses were transparent; however, micrographs of their fracture surfaces showed some crystallinity. Properties were determined as a function of the N and Na 2 O contents of the glasses. Compared with N‐containing silicate glasses, the properties of borate glasses are much less changed by the nitrogen introduced.
