Abstract

Experimental investigations have been carried out to study the phase separation process in the TeO2-B2O3 system. It was found that the phase diagram is of a eutectic-like type (monotectic invariant reaction), with a wide region of stable and metastable phase separation. During the cooling of the melts two phases are obtained. One has a high TeO2 content and is a transparent glass. The other, richer in B2O3, is opaque and in structure constitutes a complicated microheterogeneous system.
