Abstract:

Effort was directed toward the completion of the phase diagram for the system SiO2-B2O3 and clarification of related problems. The most noticeable change in the diagram is the extension of the postulated two-liquid area towards the B2O3 side. X-ray studies of the Si-B-O system were made and 3 possible isothermal diagrams for the system are presented. In the system Al2O3-B2O3 final runs were made in the high B2O3 portion of the diagram. The relation of 2 of the 3 compounds in this system were established. Preliminary work is continuing on the ternary system Al2O3-B2O3-SiO2.
