SiC Synthesis Using Natural Mg-Silicates
(Science of Sintering, 2012)
The silicon carbide powders are prepared by carbothermal reduction of domestic mineral resources (white and brown sepiolite), at relatively low temperatures (1200 - 1600 degrees C). Carbothermal reduction process is greatly ...
Structure and surface composition of NiCr sputtered thin films
(Science of Sintering, 2006)
Thin films of nichrome were deposited by d.c. sputtering of a target (80%Ni - 20%Cr w.t.) by Ar+ ions at a working pressure of 10(-1) Pa and at room temperature. The phase composition and grain size were studied by X-ray ...
Crystal structure analysis of Nd-doped ceria solid solutions
(Science of Sintering, 2008)
This paper deals with Nd-doped ceria solid solutions: Ce(1-x)Nd(x)O(2-delta) with x ranging from 0 to 0.25. Six different powders were synthesized by applying the method based on self-propagating room temperature reaction ...
Preparation of biomorphic SiC ceramics
(Science of Sintering, 2008)
This paper deals with a new method for producing non-oxide ceramic using wood as a template. SiC with a woodlike microstructure has been prepared by carbothermal reduction reactions of Tilia wood/TEOS composite at 1873K. ...
Study of Dielectric Behavior and Electrical Properties of Hematite alpha-Fe2O3 Doped with Zn
(Science of Sintering, 2012)
The effects of Zn-doping on the dielectric behavior and electrical properties of bulk alpha-Fe2O3 have been studied. X-ray diffraction analysis revealed the presence of two phases in all samples: hematite and spinel ZnFe2O4, ...
Y3Al5O12:Re3+ (Re=Ce, Eu, and Sm) Nanocrystalline Powders Prepared by Modified Glycine Combustion Method
(Science of Sintering, 2014)
Yttrium aluminum garnet doped with rare earth ions (Ce3+, Eu3+ and Sm3+) was prepared by modified glycine method. Ce3+ as a dopant was used in four different concentrations (Y3-xCexAl5O12; x(%) = 1, 2, 3, 5), while doping ...
Structural Characterization of the Nickel Thin Film Deposited by GLAD Technique
(Science of Sintering, 2013)
In this work, a columnar structure of nickel thin film has been obtained using an advanced deposition technique known as Glancing Angle Deposition. Nickel thin film was deposited on glass sample at the constant emission ...
Mechanical Properties Correlation to Processing Parameters for Advanced Alumina Based Refractories
(Science of Sintering, 2012)
Alumina based refractories are usually used in metallurgical furnaces and their thermal shock resistance is of great importance. In order to improve thermal shock resistance and mechanical properties of alumina based ...
Structure and Magnetic Investigations of Ca1+xYxMnO3 (x=0, 0.1, 0.2, 0.3) and Mn4+/Mn3+ Relation Aanalysis
(Science of Sintering, 2010)
Structure and magnetic features of nanostructured materials with general formula Ca1-xYxMnO3 (x = 0; 0.1; 0.2; 0.3) were investigated. Goldschmidt tolerance factor, G, and global instability index, GII were calculated for ...
Mechanical Properties of Biomorphic Silicon Carbide Ceramics
(Science of Sintering, 2011)
Bioinorphous beta-SiC ceramics were produced from linden wood by impregnation with tetraethyl orthosilicate (TEOS), followed pyrolysis and high temperature treatment at 1580 degrees C. Six specimen groups included charcoal ...
