Abstract

FIELD: glass materials. SUBSTANCE: glass has, wt.-%: PbF29.27-58.01; BO15.65-19.30; ZnO 0.2-1.0; CdO 0.1-1.5; BiO23.18-53.38; AlO0.05-4.18; CuO 0.01-1.5; NiO 0.01-0.50. Properties: TCLE, α(10 - 144)·101/degree, temperature of softening start is 290-358 C, temperature of deformation start is 330-385 C, microhardness is 390-470 C, spreading temperature is 500 C, time of exposition at the spreading temperature up to the appearance of the first symptoms of crystallization is 20-300 min. Glass is used for making of magnetic heads made of ferrites or metallic alloys. EFFECT: increased crystallizing stability. 2 tbl
