Tellurite glasses have found wide applications in laser, nonlinear optics and optical
communication. This paper describes the role of Bi 2 O 3 on the physical and optical …

Bi2O3 catalysts have been prepared via precipitation method by using Bi (NO3) 3· 5H2O as
a starting material and NaOH as the precipitating agent. The influence of bismuth …

Abstract Ge 0.77 Ag 0.1 Sb 0.13 Te 1 alloy was fabricated by a novel two-step route. Firstly,
oxide reagents were melted at high temperature and quenched into pellets. The pellets were …

The influence of heating and reduction processes on the structural, thermal and mechanical
properties of bismuth-silicate glasses has been investigated. Two compositions of glasses …

A reduction of bismuth oxide in hydrogen atmosphere was investigated. The reaction was
performed with a material in various structural forms: powder: with micrometric grains …

A very large melting–solidification hysteresis of Bi nanoparticles embedded in a bulk alkali
germanate glass is reported. Heating and cooling cycles are reproducible and show …

We report on the effect of hydrogen annealing on the optical properties of bismuth-doped
sodium aluminosilicate glasses. The redox state of bismuth in the as-melted glasses is …

A novel method of thermoelectric materials fabrication has been developed. Oxide reagents
have been melted at high temperature in air, quenched, milled to powder and reduced in …

Ionic conductivities in the bismuth germanate silicate (BGSO) glasses have been
investigated in the frequency range 100 Hz to 15 MHz and in the temperature range from …

SiO2–PbO–Bi2O3 glasses having the composition of 35SiO2–xPbO–(65− x) Bi2O3 (where
x= 5, 20 and 45; in mol%) have been prepared using the conventional melting and …
