Abstract : The report summarizes the work done in the phase equilibrium investigations of the systems SiO2-B2O3, Si-B-O, Al2O3, and Al2O3-B2O3-SiO2. Refinement of the SiO2-B2O3 phase diagram was carried out. The elimination of some anomalous results from earlier work will facilitate the attainment of a satisfactory diagram for this system. Work in the Si-B-O system concerned the determination of phase compatibilities at 1300 C. Evidence that the system Si-B is considerably more complex than generally indicated was obtained. A dissertation covering the findings in the systems Al2O3-B2O3 and Al2O3-B2O3-SiO2 has been completed. (Author)
