Glass formation and glass structure of the BiO1.5—PbO—CuO system

Glass formation and glass structure of the BiO1.5—PbO—CuO system The glass-forming region of the BiO1.5—PbO—CuO system has been determined by the melt-quenching technique. The glass transition temperatures, Tg, and the first crystallization peak temperatures, Tx1, are around 240°C and 285°C, respectively. The glass structure consists of [BiO3] and [BiO6] units, and the conversion between these polyhedra mainly depends on the CuO and PbO content. The covalent characteristic in the infrared absorption spectra of the [PbOn] pyramidal units becomes significant when the glass contains more PbO. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Materials Science Springer Journals

Abstract

The glass-forming region of the BiO1.5—PbO—CuO system has been determined by the melt-quenching technique. The glass transition temperatures, Tg, and the first crystallization peak temperatures, Tx1, are around 240°C and 285°C, respectively. The glass structure consists of [BiO3] and [BiO6] units, and the conversion between these polyhedra mainly depends on the CuO and PbO content. The covalent characteristic in the infrared absorption spectra of the [PbOn] pyramidal units becomes significant when the glass contains more PbO.
