Characterization and phase evolution of cordierite based glass synthesis from pure oxide and minerals
Banjuraizah, Johar; Hasmaliza, Mohamad; Zainal Ariffin, Ahmad (Trans Tech Publications, Switzerland, 2011)α Cordierite is very important phase in MgO-Al2O 3-SiO2 system because of their very outstanding thermal, chemical and electrical properties. In this presents study non-stoichiometry cordierite (MgO:Al2O3:SiO2 = 3:1.5:5) ... -
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
Banjuraizah, Johar; Hasmaliza, Mohamad; Zainal Ariffin, Ahmad (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 melting temperatures on the crystallization and densification of 2.8MgO•1.5Al2O3•5SiO2 glass-ceramic synthesized from mainly talc and kaolin
Banjuraizah, Johar; Hasmaliza, Mohamad; Zainal Ariffin, Ahmad (Elsevier B. V., 2010-02-03)Single phase α-cordierite with low sintering temperature was produced from 2.8MgO·1.5Al2O3·5SiO2 chemical formulation using mainly talc and kaolin. The effect of melting temperature to the densification, crystallization ... -
The effects of Al2O3 amount on the microstructure and properties of Fe-Cr matrix composites
Saidatulakmar, Shamsuddin; Shamsul Baharin, Jamaludin, Prof. Dr.; Zuhailawati, Hussain; Zainal Ariffin, Ahmad (Springer, 2010-12)Iron based matrix composites reinforced with 5 to 25 wt pct of Al2O3 particles were fabricated using the powder metallurgy method. The samples were prepared by mixing at 250 rpm for 30 minutes, uniaxially pressing at 750 ... -
Measurement on strain rate sensitivity and dynamic mechanical properties of various polymeric materials
Mohd Firdaus, Omar; Hazizan, Md Akil; Zainal Ariffin, Ahmad (Trans Tech Publications, 2011)Strain rate sensitivity and dynamic mechanical properties of polymeric materials are affected to a certain extent especially by the rate of loading. However, there is limited number of works reported on that particular ... -
Research advances of composite solder material fabricated via powder metallurgy route
Mohd Arif Anuar, Mohd Salleh; Muhammad Hafiz, Hazizi; Mohd Mustafa Al Bakri, Abdullah; Nik Noriman, Zulkepli; Ramani, Mayapan; Zainal Ariffin, Ahmad (Scientific.Net/Trans Tech Publications, 2012-12)Researches and studies on composite solder have been done by many researchers in an effort to develop viable lead-free solders which can replace the conventional lead-based solders as lead is considered as toxic. Solder ... -
Research development of solder materials and its intermetallic compound (IMC) study
Mohd Arif Anuar, Mohd Salleh; Najib Saedi, Ibrahim; Saud, N.; Mohd Mustafa Al Bakri, Abdullah; Nik Noriman, Zulkepli; Ramani, Mayapan; Zainal Ariffin, Ahmad (Scientific.Net/Trans Tech Publications, 2012-12)Nowadays, the formation and the subsequent growth of the intermetallic compounds (IMCs) and the development of new lead-free solder systems is a major issue in soldering. The excessive growth formation of intermetallic ... -
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 xMgO-1.5Al2O3-5SiO2 (x = 2.6-3.0) system using mainly talc and kaolin through the glass route
Banjuraizah, Johar; Hasmaliza, Mohamad; Zainal Ariffin, 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 ...
