The aim of the presented research was to analyze ceramic material based on cordierite as a function activation time and sintering temperature. Three-component oxide mixture prepared (MgO + Al2O3 SiO2 in ratio 2:2:5). To decrease temperature, 10 mass % Bi2O3 added this mixture. mixtures were mechanically activated for 5 240 minutes ball mill. Activated sintered at temperatures 1173-1573K. XRD me...

In order to attain glasses with ultra dispersions properties, different heavy metal oxides were used. The desired glasses were obtained from the addition of high amounts of PbO and Bi2O3 to B2O3 based glasses. Refractive index measurements were carried out accurately at different wavelengths by the minimum angle of deviation in prisms method employing a spectrometer. Results indicated that, as ...
