Compositions from the systems Pb-Mn-B-O and Pb-Mn-Te-0 are used to synthesize glass-ceramics obtained by solid state reactions and from supercooled melts. By casting on a metal plate or by quenching with the aid of twin rollers the melts are cooling. The glass-crystalline materials are obtained after heating glasses from the combination of PbO-MnO-B203 and PbO-MnO-TeO2 with the addition of La203 from 10 to 50 wt.% and the formation of the crystalline phases is determined.
