Mechanochemical Synthesis of Double Hydroxides
Tập 8 - Trang 251-253 - 2000
It has been demonstrated that the formation of magnesium-aluminium double
hydroxides [Mg(1 − X)Al X (OH)2] X+(A n− X/n ) • m H2O, (A–Cl−, NO− 3, SO2− 4)
occurs during mechanical activation of the mixture of magnesium hydroxide
(brucite) with aluminium chloride, nitrate and sulphate in high-energy
planetary-type activators. The effect of activation time on the formation of the
double hydroxide has ...
Conversion of the Echinoderm Mellita eduardobarrosoi Calcite Skeleton into Porous Hydroxyapatite by Treatment with Phosphated Boiling Solutions
Tập 7 - Trang 211-219 - 1999
The influence of the boiling solution technique (a nonhydrothermal wet
treatment) in the formation of hydroxyapatite (HA) from a novel source, an
echinoderm known as Mellita eduardobarrosoi, whose skeleton contains calcite as
an inorganic constituent, was investigated. The experimental plan explores the
conversion using a batch boiling system composed of KH2PO4 + KOH aqueous
solutions at initial p...
MSR Reduction of Hexachlorobenzene
Tập 8 - Trang 295-300 - 2000
This paper deals with the mechanochemical degradation of hexachlorobenzene over
Li, Na, K, Mg, Ca, Ba, Ti, and W. Apart from the mixtures containing Ti and W,
the other systems react in a combustive mode leading to the chlorides and the
carbides of the inorganic substrates. Reaction stoichiometries and heats were
experimentally determined. The activation time required to ignite the reaction
decrea...
Reaction Bonding of Three-Layer Alumina-Based Composites
Tập 7 - Trang 195-203 - 1999
Three-layer alumina-based composites with Al2O3-containing mullite as the outer
layer and ZrO2-containing alumina as the inner layer were fabricated by
die-pressing and reaction bonding. The effects of the outer-layer compositions
on the densification behavior of three-layer composites were investigated. The
existence of residual stresses in the layers was verified using indentation
methods. Compa...
Chemical Durability of Waste Fluorescent Glass and Shell–Derived Glass-Ceramics
Tập 10 - Trang 37-42 - 2002
In order to obtain glass-ceramics reinforced by β-wollastonite, pressed
specimens prepared by powdered waste fluorescent glass and refuse shell dumped
in the seashore were heat-treated at 800°C, 900°C, and 1000°C. Chemical
stability of the heat-treated specimens was analyzed by weight changes and by
observation of surface morphology and composition, by field-emission scanning
electron microscopy a...
High-Pressure Processing and Characterization of Fe–High-C/N Alloys
Tập 6 - Trang 147-154 - 1998
A new process has been developed that results in (i) enhanced nitrogen addition
to ferritic iron–carbon alloys and (ii) melt-casting in a single operation. This
new processing technique enables Fe–C alloys to retain high nitrogen
interstitial concentrations and to reduce significantly, and possibly eliminate,
carbide formation. In this study two commercial-grade, steel alloys were cast
under eleva...
Microwave Sintering of Alumina Using Four Single-Cavity Modes
Tập 7 - Trang 159-166 - 1999
In this study, alumina ceramics were sintered with 2.45-GHz microwaves in a
cylindrical single-mode microwave cavity using four resonant cavity modes:
TM111, TE112, TE113, and TM013. The mass density and grain size of sintered
specimens were found to be relatively uniform with respect to both (i) the
radial position within a given specimen and (ii) the cavity mode used to sinter
the specimen. Howe...
Combustion Synthesis of Glass (B2O3-Al2O3-MgO)-Ceramic (TiB2) Composites
Tập 10 - Trang 163-174 - 2002
The combustion synthesis, or self-propagating high temperature synthesis (SHS),
technique has been used to produce glass ceramic composites that have a glass
matrix based on B2O3-MgO-Al2O3and a crystalline ceramic phase of TiB2.
Conditions for producing glassy materials by the SHS technique are discussed and
the thermodynamics of these combustion reactions are analyzed. The combustion
characterist...
Mössbauer Studies in the Mechanochemistry of Spinel Ferrites
Tập 8 - Trang 155-166 - 2000
Mössbauer spectroscopy can provide information on a large variety of
mechanochemical processes in solids. In this overview, selected examples are
presented of Mössbauer studies of homogeneous and heterogeneous mechanochemical
reactions in spinel ferrites. Several interesting features are involved in the
work, e.g., mechanically induced cation redistributions, changes of
nearest-neighbor configurat...
Selective Formation of Titanium Silicide by Chemical Vapor Deposition Using Titanium Halides and Silicon Wafer as the Precursors
- 1998
Titanium silicide thin films were formed on Si substrate by reaction of TiX 4
(X=C1, Br) with Si under different experimental conditions. The Si consumption
and titanium silicide obtained were calculated by the film thickness. In some
reactions, titanium silicide thin film was found not only on the Si substrates
but also on the SiO2 wall at the outlet of the reaction chamber. The quantity of
Si co...
