Abstract:

A number of refractory materials were examined to determine their possible usefulness as materials for crucibles for melting, fining, and drawing high-silica glass compositions. NbB2 gave the most promising results of the materials examined. Time and temperature relationships as well as variations in bath composition were investigated in an effort to improve premelt characteristics. The addition of V2O5 was particularly effective. It had been conceived that a well-fined premelt should be a better starting material for fiber drawing than an unreacted batch composition. Fiber drawing studies, however, showed no improvement in either the drawing characteristics or in the physical characteristics of fiber when wellfined premelt was used. Author
