The effect of CaO∖SiO 2 molar ratio on the electrical properties of some glass materials was examined, using the impedance spectroscopy, at different frequency ranges, from 100 Hz up to 5 MHz. Also, a trial was accomplished to study the influence of CaO∖SiO 2 molar ratio on some physical properties such as density, micro-hardness and bending strength.

Novel glass ceramics for LTCC applications with high flexural strength can be achieved by CaO-MgO-ZnO-SiO2(CMSZ) glass cofiring with Al2O3. The sintering shrinkage behavior, crystalline phases, mechanical and dielectric properties, and thermal expansion of the CMZS/Al2O3 glass ceramic were determined. The X-ray diffraction results revealed that multiphases (CaMgSi2O6, Al2Ca(SiO4)2 and …

According to the phase diagrams of CaO-SiO2, CaO-B2O3 and SiO2-B2O3, the structural units of molten slag were confirmed. The activity model of CaO-SiO2-B2O3 ternary system was established with the ion and molecule coexistence theory. The activities of CaO, SiO2, B2O3, CS, C2S, C3B, C2B, CB and CB2 in molten slag were calculated by the model.

3. Results and discussion The Raman spectra of CaO-SiO2 glasses are shown in fig. 1. The band near 350 cm-J due to the vibration of the Ca-O bond [9] shifts slightly to higher frequencies with the CaO content. The band near 500 cm- ~ due to the bending vibration of the Si-O bond shifts markedly to higher frequencies with an increase of the CaO ...

Laboratory-scale experiments were performed to investigate the deoxidation of H13 tool steel with CaF2-MgO-Al2O3-CaO-SiO2 slags at 1873 K. The calculation of thermodynamics and kinetics was also verified through the experimental results. The results show that [Si]-[O] reaction is the control reaction, and with the increase of basicity of slag, the limitation of deoxidation was decreased. The ...
