Rietveld quantitative phase analysis of non-stoichiometric cordierite synthesised from mainly talc and kaolin: Effect of sintering temperature
Banjuraizah, Johar; Hasmaliza, Mohamad; Zainal Ariffin, Ahmad (Trans Tech Publications, Switzerland., 2011)Indialite or α-cordierite was synthesized by glass crystallization method using mainly talc and kaolin and with small amount of MgO, Al 2O3, SiO2 to compensate the chemical formulation of non-stoihiometric compositions of ... -
Synthesis and Characterization of Stabilized Zirconia Toughened Alumina (ZTA) Doped Niobium Pentoxide (Nb2O5)
Banjuraizah, Johar; Zul Azhar, Zahid Jamal; Ahmad, Z. A. (EDP Sciences, 2016)The main target of this research is to study the mechanical properties of the Nb2O5 doped with alumina-zirconia composites. Pellets form samples of ZTA (5YSZ) doped niobium pentoxide in varied amount of 0 wt%, 0.3 wt%, 0.5 ... -
Synthesis and characterization of xMgO-1.5Al2O3-5SiO2 (x = 2.6-3.0) system using mainly talc and kaolin through the glass route
Banjuraizah, Johar; Hasmaliza, Mohamad; Zainal Arifin, Ahmad (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 ... -
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
Banjuraizah, Johar; Hasmaliza, Mohamad; Zainal Arifin, Ahmad (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 ...
