The most promising method for obtaining a large variety of non-oxide products having important technical uses is carbothermal-reduction reaction (CRR). By using this procedure, SiC and ZrC/SiC powders are obtained from ...

In this work, sol gel method was used to prepare FexOy/Gd2O3/SiO2 composite system starting from two different iron precursors: iron nitrate and iron oxide xerogel. The obtained samples were subjected to heat treatment at ...

Fine tungsten carbide (WC) powder was prepared by solid state reaction between tungsten powder (W) and activated carbon cloth as a new carbon (C) source. The effect of temperature and time of heat treatment as well as the ...

Investigations of the high-pressure sintered nanocrystalline mullite powder are presented. The synthesized mullite powder with crystallite size of 51 nm was densified by using high-pressure anvil-type with hollows apparatus ...

Calcium hydroxyapatite (CHA), as one of the most important ceramic materials in bone tissue engineering, was used as a delivery system for tigecycline, a potential antibiotic in treatment of osteomyelitis. Tigecycline, in ...

Monoclinic celsian has been prepared from Ba-LTA zeolite precursor. The Ca2+-texchanged hexacelsian (HCCa,) synthesized from Ba-LTA zeolite precursors was used for preparation of monoclinic celsian (MCCa). The partially ...

VO2(B) has been successfully synthesized by simple, facile and environmental friendly one-step solvothermal method using V2O5 and ethanol as a starting agent. Obtained micrometer-sized powder was composed from mutually ...

A new technology for radionuclide trapping which is based on bio-templating approach was proposed in this paper. Porous oxide ceramics was prepared by wet impregnation of biological template with water solution of cerium ...

Structural, electrical and magnetic properties of nickel manganite ceramics obtained by sintering fine powders prepared by a complex polymerization method are given in this work. The phase composition of the synthesized ...
