ABSTRACT:
Fibers composed of mixtures of refractory metal oxides, other than silica, are treated by a process involving a drawing step to markedly increase the modulus of elasticity of the fibers. The compositions of the fibers to which the process is applied are typically mixtures of refractory vitreous metal oxides such as calcia, alumina, verylia and the like which are devoid or nearly devoid of silica or other network formers but may be a single such oxide mixed with no more than small or insignificant amounts of such other oxides.
