Synthesis and characterization of wollastonite produced from Malaysian limestone and silica sand
(Universiti Malaysia Perlis, 2010-06-09)
Wollastonite was synthesised via
solid state reaction using Malaysian limestone
and silica sand as the raw materials. It was
synthesised at 1100oC, 1200oC, 1300oC,
1400oC and 1450oC. The products obtained
were ...
XRD analyses of InxGa1-xN (0.20 x 0.80) ternary alloys
(Universiti Malaysia Perlis, 2010-06-09)
We present the structural properties
of ternary InxGa1-xN (0.20 x 0.80) alloys
grown on sapphire substrate by plasma-assisted
molecular beam epitaxy. High resolution X-ray
diffraction (HR-XRD) analyses were used ...
Characterization of -TCP/alumina composite
(Universiti Malaysia Perlis, 2010-06-09)
Calcium phosphate composite of -tricalcium
phosphate ( -TCP) matrix with different amount of
alumina (Al2O3) was studied. -TCP powder was
initially prepared via mixing calcium carbonate and
phosphoric acid to form ...
Structural properties studies of GaN on 6H-SiC by means of X-ray diffraction technique
(Universiti Malaysia Perlis, 2010-06-09)
Epitaxial growth of GaN has become an interest topic in term of light emitting device fabrication. Most of the commercial GaN based device is normally grown on sapphire substrate. For power device application, SiC has been ...
Effect of sintering temperature on the properties of porous alumina synthesized through soft combustion for biomedical application
(Universiti Malaysia Perlis, 2010-06-09)
This paper describes the effects of
sintering temperature on porous structure of
alumina produced by using different types of fuels
(urea and glycine) through a soft combustion
reaction. In the present work, the effect ...
Mineralogical component of palm oil fuel ash with or without unburned carbon
(Universiti Malaysia Perlis, 2010-06-09)
The purpose of this paper is to investigate the mineralogical components of palm oil fuel ash (POFA) with or without unburned carbon by using semi-quantitative X-ray diffraction (XRD). Original POFA taken from palm oil ...
Formation of TiC-reinforced iron based composite through carbothermal reduction of hematite and anatase
(Universiti Malaysia Perlis, 2010-06-09)
In this research carbothermal reduction of mechanical activated hematite (Fe2O3), anatase (TiO2) and graphite (C) was investigated. The mixtures of raw materials with composition of Fe-20vol%TiC were mechanically activated ...
Deposition of some transparent conducting oxide thin films by a simple spray pyrolysis technique and their characterizations for optoelectronic applications
(Universiti Malaysia Perlis, 2010-06-09)
In this study, spray pyrolysis method has
been employed for the deposition of
some transparent oxide thin films like
ZnO, CdO and SnO2 onto glass substrate
under atmospheric pressure using zinc
acetate, cadmium acetate ...
