Thermal expansion coefficient and dielectric properties of non-stoichiometric cordierite compositions with excess MgO mole ratio synthesized from mainly kaolin and talc by the glass crystallization method
(Elsevier B. V., 2010-04-02)
α-Cordierite phase in non-stoichiometric cordierite formulations was synthesized using mainly kaolin and talc, without sintering aids, via the glass crystallization route. MgO mole ratios in the formulations were varied ...
Crystal structure of single phase and low sintering temperature of α-cordierite synthesized from talc and kaolin
(Elsevier B.V., 2009-08)
Cordierite body with the formulation of 2.8MgO·1.5Al2O3·5SiO2 was prepared from talc and kaolin as the basic raw materials. Following glass crystallization technique the glass powder was successfully heat treated at 900 ...
Effect of excess mgo mole ratio in a stoichiometric cordierite (2MgO·2Al2O3·5SiO 2) composition on the phase transformation and crystallization behavior of magnesium aluminum silicate phases
(The American Ceramic Society, 2011-05)
The effect of excess MgO, 2.0-4.0 mol ratios on the crystallization behavior and purity of Iμ-cordierite was investigated using X-ray diffraction (XRD), differential thermal analyzer, and TGA. Quantitative XRD, the Rietveld ...
Effect of impurities content from minerals on phase transformation, densification and crystallization of α-cordierite glass-ceramic
(Elsevier B.V., 2011-07-14)
α-Cordierite glass-ceramic was produced through crystallization of glass compacts made of milled glass frits. A comparative investigation between two different initial raw materials to synthesize α-cordierite glass-ceramic ...
Synthesis and characterization of xMgO-1.5Al2O3-5SiO2 (x = 2.6-3.0) system using mainly talc and kaolin through the glass route
(Elsevier B.V., 2011-10-03)
Three non-stoichiometric cordierite with compositions of xMgO-1.5Al2O3-5SiO2 (x = 2.6-3.0 mol) were synthesized using mainly talc and kaolin through the glass route. The densification and crystallization behaviors of these ...
