The influence of Bi2O3 and melting temperature on the thermal structural properties xBi2O3-(60-x) ZnO-40B2O3 glasses has been investigated in this study. It is expected that these factors can be used to control degree reduction Bi2O3, relationship between color change process for bismuth glass discussed. Due high-temperature melting, bismuth-doped borate have changed into dark/black from origin...

Molybdates from A2Mo3O12 family have been widely investigated due to its low sintering temperature, thermal expansion coefficient, and dielectric loss. Fe2Mo3O12 (FMO) is an oxide this used in the catalytic field. The aim of work evaluate influence Bi2O3–B2O3 as a aid microstructure properties FMO. diffraction results showed that FMO with monoclinic structure phase was obtained after calcinatio...

Bi4V2O11 (BiVO) is an Aurivillius-type layered compound that exhibits a red color, and has been attracting attention for its non-toxicity. In this study, we have synthesized variety of metal oxide-doped Bi4V2O11, aimed to evaluate the effect doped element on color tone pigments. Bi2O3 V2O5 were weighed 2:1 in mole fraction mixed dry-ball mill with zirconia media 10 min. Next, transition oxides ...

The novelty of this paper is due to the investigation of the possibility of reaching a reliable global effective model of temperature dependence on the optical properties, based on automated neural network (ANN). For this approach, starting with a series of experimental data set of the measured reflectance magnitudes we built and studied 20 different ANN with RBF and MLP structure and with diff...
