The densification and crystallization behaviors of these glass powders were investigated using DTA, dilatometer, and XRD. Samples were then heat treated at 900 °C for 2 h and further analyzed using XRD, CTE, FESEM, density and porosity tests, and also dielectric test to further investigate their properties. The 2.8MgO·1.5Al2O3·5SiO2 glass composition fully densified and crystallized into high purity α-cordierite at the heat treatment temperature. It exhibited lower CTE and dielectric constant compared to other composition, making it suitable for high frequency applications. Other formulations which contain multi crystalline phases require much higher temperatures for densification. The CTE value depends on the type of crystalline phase which exist in the sample, while the dielectric constant decreased with increasing MgO amounts in the sample compositions. 2011-10-24T03:21:08Z 2011-10-24T03:21:08Z 2011-10-03 Article Materials Chemistry and Physics, vol. 129 (3), 2011, pages 910-918 0254-0584 http://www.sciencedirect.com/science/article/pii/S0254058411004214 http://hdl.handle.net/123456789/14872 en Elsevier B.V.
