Abstract : The chalcogenide glass system studied this quarter was formed from silicon (Group IV element), antimony (Group V element), and selenium (the chalcogen). The system was studied in essentially the same manner as the silicon-antimony-sulfur system reported in the first quarterly report. The results obtained from 42 samples of different composition are given. All sample numbers of compositions that formed glasses are marked with an asterisk. The measured and corrected softening points of each glass are given and range from a maximum of 490 C down to a minimum value of 163 C for a 85% selenium glass. The softening points were measured using the apparatus described. (Author)
