Aluminothermic Reduction of Zirconia
Journal of the European Ceramic Society, 2004Results are presented for the reaction of aluminium metal with zirconia ceramics under (reducing) sintering conditions. Aluminothermic reduction is a form of self-sustaining high-temperature synthesis (SHS). During reaction the principal phase formed is zirconium monoxide which is shown to have a rock-salt cubic structure and a unit-cell dimension of 0.

Aluminothermic reduction of tungstic oxide
Journal of the Less Common Metals, 1967Abstract A method for the preparation of massive tungsten metal by aluminothermic reduction of its trioxide in a closed, magnesia-lined reactor, with provision for the formation of a low melting “Al 2 O 3 -Al 2 S 3 ” slag, has been developed. The presence of a small amount of a mixture of calcium and sulphur was found to be necessary in the charge to

Kinetics of Low-Temperature Aluminothermic Reduction of Iron Tantalate
Inorganic Materials: Applied Research, 2021The kinetics of low-temperature (900 – 1180 °C) reduction of iron tantalate (98.2 wt % FeTa2O6, 1.8 wt % Ta2O5, particle size < 0.1 mm) by excess aluminum (particle size < 0.14 mm) at the molar ratio Al:FeTa2O6 = 6 was studied. According to differential scanning calorimetry and X-ray powder diffraction, reduction is almost completed at 1180 °C ...

Aluminothermic SHS reactions: effect of scaling
International Journal of Self-Propagating High-Temperature Synthesis, 2011The influence of scale effects-sample diameter, sample length, and sample mass—on combustion of CrO3-Cr2O3-C-Al, CrO3-Cr2O3-B2O3-Al, and NiO-Cr2O3-Nb2O5-WO3-MoO3-C-Al green mixtures was explored. Suggested was a qualitative model based on the behavior of the melt within and behind of the combustion front.

Subchloride aluminothermic extraction of titanium from chlorides
Theoretical Foundations of Chemical Engineering, 2008The results of thermodynamic calculations and experiments show the possibility of obtaining (i) titanium aluminide (TiAl3) by reducing titanium tetrachloride or subchloride (TiClx, x ≤ 4) vapor by liquid aluminum and (ii) metallic titanium by reducing titanium chloride vapors with gaseous aluminum subchlorides (AlClx, x < 3) in a temperature range of ...
