Research ArticleOpen accessIn the keywordsHigh Saturation Induction for Bi-Substituted Yttrium Iron Garnet Prepared Via Sol Gel TechniqueNoorhana Yahya, Goh Kah HeanY3.0-xBixFe5O12 samples (x = 0.2 and 0.4) were prepared via novel sol-gel and conventional solid-state techniques. The effect of bismuth in both techniques was investigated in terms of shrinkage, density, hysteresis and initial permeability. Sharp and clear diffraction XRD lines with highest peak appear at about 32° of the 2θ¸, for all the powders sintered at 900°C and 1250°C for … …American Journal of Applied Sciences, Vol. 4, Issue 2 · 28 Feb 2007 · 7,594 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSynthesis of Al3Fe5O12 Cubic Structure by Extremely Low Sintering Temperature of Sol Gel TechniqueNoorhana Yahya, Ramadan A.H. Masoud, Hanita Daud et al.Problem statement: Fabrication of nano materials particularly nano inductors at low sintering temperature remains a challenge. This study was carried out as our initial response to obtain a nano-size inductors, which is aluminium iron garnet using low sintering temperature. Approach: The aluminum iron garnet (Al3Fe5O12) nano crystals were prepared by sol-gel technique. The starting solution is a mixture of iron … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,563 accessesView PDF Cite
