Effect of BaO on crystallization, sintering, and properties of MgO-Al2O3-SiO2 glass–ceramics

Effects of Nd2O3 Doping Levels on the Sintering, Microstructures, and Dielectric Properties of MgO–Al2O3–SiO2 Glass‐Ceramics

“…Chen et al [ 13 ] concluded that BaO improved the sintering performance of the MAS glass‐ceramics and increased their flexural strength, which was consistent with the findings of Zhang. [ 14 ] Xu et al [ 15 ] investigated the effects of the MgO/SiO 2 ratio and Al 2 O 3 content on the crystallization behaviors, microstructures, and thermal expansion coefficients of glass‐ceramics. These results showed that decreasing the Al 2 O 3 content had a greater effect on the melting temperature and liquid viscosity than increasing the MgO/SiO 2 ratio and that the decreased Al 2 O 3 content had a significant effect on the liquid phase content of cordierite, which dominated the crystal growth behavior of the cordierite.…”
