Band structure, density of states, and crystal chemistry of ZrGa₂ and ZrGa₃ single crystals
(Elsevier, 2013-04)Using FP-LAPW Method we have performed calculations of the band structure of the ZrGa₂ and ZrGa₃ crystals. The all-electron full potential linearized augmented plane wave method was used to solve the Kohn Sham DFT equations. ... -
CdS film thickness characterization by R.F. magnetron sputtering
(American Institute of Physics, 2009-06-01)In this work, cadmium sulphide (CdS) target with 99.999% purity was used as a target in RF magnetron sputtering. The sputtering experiment was conducted onto silicon oxide substrates at different temperatures ranging from ... -
Comparative Study of Clinker’s Transformation at Different Temperature Zone During Cement Production
(Science Publications, 2007)Chemical composition analysis using x-ray fluorescence is one of the important quality analysis for examining of cement and widely used in cement industries for a long time as a tool to estimate phase composition. X-ray ... -
Correlation between the calcination and sintering temperature on phase formation, microstructure and dielectric properties of SrTiO3 ceramics
(Universiti Malaysia Perlis (UniMAP), 2022-10)The aim of this work is to investigate the effect of calcination temperature (600, 700 and 800°C) and sintering temperature (1000, 1050 and 1100°C) on pure phase formation, microstructure and dielectric properties of ... -
The effect of stoichiometry to the dielectric properties of barium titanate
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)Due to the high dielectric constant, barium titanate (BT) has many potential applications in electronic industry. This paper focuses on the effect of different ratio between barium (Ba) and titanium (Ti) to the production ... -
The effects of Fe additions on the liquid phase sintering of W- bronze composites
(Elsevier BV, 2009)In this investigation, experiments were conducted to evaluate the effects of Fe additives in the range of 1-5 wt.% on the densification of different compositions of W-pre-alloy bronze compacts sintered isothermally at ... -
Influence of milling conditions on the mechanochemical synthesis of CaTiO3 nanoparticles
(Elsevier, 2009)The mechanochemical synthesis of calcium titanate (CaTiO3), was carried out in a planetary mill by varying the milling time and mill rotational speed at three levels. CaCO3 and TiO2 were used as the starting materials. ... -
Single-crystal oxoborate (Pb 3O) 2(BO 3) 2WO 4: Growth and characterization
(Elsevier Ltd, 2012-09)An oxoborate, (Pb 3O) 2(BO 3) 2WO 4, has been prepared by solid-state reaction methods below 620°C. Single-crystal XRD analysis shows that it crystallizes in the orthorhombic group Cmcm with a = 18.480(4) , b = 6.3567(13) ... -
