New Facts about the Phase-Diagram of the BaO-SiO2 SystemGrebenshchikov, R GToropov, N A
Likewise, an analysis of the TTT diagram indicates that these oxides facilitate the complete crystallization of the glass, resulting in the corresponding glass ceramic. None of the oxides used as nucleating agents had any significant effect on GS, since the glass remained amorphous after slightly ...
摘要: 本文应用相图模型,对Na_2O—B_2O_3—SiO_2;BaO—B_2O_3—SiO_2;Na_2O—K_2O—SiO_2和CaO—MgO—SiO_2玻璃系统的性质(比重,折射率)进行了研究,应用相图模型方法的计算值和实验值比较,二者在变化的规律性方面,完全一致.相图模型认为:玻璃和晶体具有相似的结构,多成分的玻璃则是相图中最邻近的...

Correlation between the Viscosity of Glasses of the System Na2O-BaO-SiO2 and the Phase DiagramMazurin, O VTret'yakova, N I
The resulting equations represent the thermodynamic and phase diagram data for the alkaline-earth oxide-silica systems within error limits for most of the experimental data. In particular, the measured limiting liquidus slope, at X SiO 2 = 1, is well reproduced....
Phase equilibria in the system BaO-SrO-SiO2 in air were established using conventional solid-state techniques. The phase relations in the boundary system SrO-SiO2 were completed by determining the liquidus temperatures for the SrO-rich portion of the diagram. The known compounds, SrSiO3, Sr2SiO4...
By comparison, alloying of Au with Sb does not occur according to the phase diagram. Instead, a thermal treatment at temperatures slightly above T g leads to nanocrystalline, spherical Au particles. Hence, alloying and subsequent decomposition of the alloy is a prerequisite for the formation of ...
Phase equilibrium diagramFour compositions in the BaO–Al2O3–SiO2 system modified with B2O3 were investigated with regard to their use as glassy seals in anode supported SOFC or iT-SOFC. The glassy system studied contains varying percentages of SiO2, Al2O3, B2O3, and high content of BaO ...
