A comparative investigation between two different initial raw materials to synthesize α-cordierite glass-ceramic using the same non-stoichiometric cordierite composition fabrication process was conducted. The existence of impurities in minerals significantly affected phase transformation, densification and crystallization behavior of α-cordierite phase. Sintering and crystallization behavior was observed by dilatometry test, non-isothermal DTA, and XRD, respectively. The existence of Fe2O3 in the minerals has resulted in greenish glass frits, while CaO, K and other impurities act as modifying oxide in glass compositions, reducing the viscosity of the glass, and thus affect phase transformation of glass. Although the dielectric loss of the sample from mineral precursors was slightly higher than the sample from reagent grade oxides, other properties gained were comparable and not varies too much. 2011-10-07T07:33:45Z 2011-10-07T07:33:45Z 2011-07-14 Article Journal of Alloys and Compounds, vol. 509 (28), 2011, pages 7645-7651 0925-8388 http://www.sciencedirect.com/science/article/pii/S0925838811009947 http://hdl.handle.net/123456789/14050 en Elsevier B.V.
