Synthesis and settings behavior of alpha-TCP from calcium deficient hyroxyapatite obtained by hydrothermal method
(Journal of Optoelectronics and Advanced Materials, 2007)
The aim of this work is the investigation of alpha-tricalcium-phosphate (alpha-TCP) formation from calcium-deficient hydroxyapatite (CDHAP), synthesized by hydrothermal method from CaCl2, EDTA, NaH2PO4 center dot 2H(2)O ...
SiC Fabrication by carbothermal reduction of sepiolite
(Journal of Optoelectronics and Advanced Materials, 2008)
In this paper, the possibility of using sepiolite as Si precursor for low temperature synthesis of silicon carbide (SiC) via carbothermal-reduction reactions was studied. A sepiolite of Serbian origin and carbon ...
Synthesis and characterization of hydrothermally obtained colloidal pseudoboehmite/boehmite
(Journal of Optoelectronics and Advanced Materials, 2009)
In this paper, the synthesis and structure of pseudoboehmite/boehmite obtained by hydrothermal method is described. The SO(4)(2-)ions were used for the colloid stabilization. The influence of the ageing time on the particle ...
Synthesis of LiMn2O4 by glycine-nitrate method
(Journal of Optoelectronics and Advanced Materials, 2003)
Glycine-nitrate method was used to synthesize lithium manganese oxides. For the molar ratio of lithium-to-manganese in precursor solution equal to 1:2 spinel LiMn2O4 was obtained. For molar ratio of 1:1 a mixture of Li2MnO3 ...
Synthesis of sillenite-type compounds from zeolite precursors: XRPD and SEM/EDS analyses
(Journal of Optoelectronics and Advanced Materials, 2008)
The paper analyze the possibility of using LTA zeolite as a precursor for obtaining sillenite phase (Bi(12)MO(20), M=Si, Ti, Ge) by hydrothermal synthesis process. The synthesis procedure involves mixing of zeolite (Na-LTA) ...
Sintered fused silica based composites
(Journal of Optoelectronics and Advanced Materials, 2008)
In present work, complex mixtures were designed based on fused SiO(2), beta-SiC and different oxide additives. The addition of Al(2)O(3) and mulite - 3Al(2)O(3) 2SiO(2) influence was investigated in order to obtain high ...
Synthesis and characterization of ordered mesoporous silica
(Journal of Optoelectronics and Advanced Materials, 2009)
Ordered mesoporous silica SBA-15 materials were synthesized by using Pluronic P123 (non-ionic triblock copolymer, EO(20)PO(70)EO(20)) as a template, under acidic condition. These materials were characterized by nitrogen ...
The synthesis and microstructure of morphogenetic SiC ceramics
(Journal of Optoelectronics and Advanced Materials, 2008)
Highly porous SiC ceramics with a wood like structure were prepared from premineralized wood template through tetraethyl orthosilicate (TEOS) infiltration. The TEOS was first decomposed to SiO2 and then in situ reaction ...
Nanosized ceria solid solutions obtained by different chemical routes
(Journal of Optoelectronics and Advanced Materials, 2008)
Nanometric size ceria powder particles were obtained by applying modified glycine/nitrate, as well as self propagating room temperature methods. The powders were doped and co-doped with rare earth cations in the concentration ...
Characterization of platinum deposited on carbon hollow fibers/carbon cryogel composites
(Journal of Optoelectronics and Advanced Materials, 2008)
Platinum supported on high surface area carbon material is one of the most intensively studied catalysts. However, physicochemical characteristics and surface chemistry of carbon influence properties of the support itself ...
