dcterms:description
Glass formation has been investigated in the Sb2O3-ZnBr2 binary system. Vitreous samples have been obtained for batches containing 20-90 mol% Sb2O3. Chemical analysis shows that bromine concentration is smaller than expected and real compositions belong to the Sb2O3-ZnBr2-ZnO ternary system. However, the discrepancy between nominal and analyzed compositions is fair for Sb2O3 content larger than 50 mol%. Optical transmission lies between 400 nm and 7 mum and refractive index ranges from 2.0 to 2.1. Glass transition occurs around 300 degreesC, and crystallization exotherm does not appear in the differential scanning calorimetry scan at 10 K s(-1) for samples containing 50-60 mol% Sb2O3. Thermal expansion varies between 120 and 220 x 10(-7) K-1 as antimony content decreases. Microhardness is close to 200 kg/mm(2). These glasses have low phonon energy and make potential materials for infrared transmission and active fibers. Glass formation has been investigated in the Sb2O3-ZnBr2 binary system.
