Abstract:

A unique glove box system has been built which permits the melting and fabrication of halide and chalcohalide glasses under controlled atmospheres. Glass fibers have been prepared inside this system and their tensile strengths and viscoelastic properties measured in situ. Further the microstructures of glasses and ceramics prepared as well as their infrared transmission were investigated without the need to expose the samples to the external atmosphere. The system has been used to perform research for the Air Force Office of Scientific Research and to train students in the preparation of ultrapure glasses and ceramics.
