In-situ fabrication of Al(Zn)−Al2O3 graded composite using the aluminothermic reaction during hot pressing

International Journal of Minerals, Metallurgy, and Materials, 2018
In this study, the fabrication of multilayer Al(Zn)–Al2O3 with different volume fractions of Al2O3 was investigated. Al and ZnO powders were milled by a planetary ball mill, after which five-layer functionally graded samples were produced through hot pressing at 580°C and 90 MPa pressure for 30 min.

Interaction of a ceramic material based on hematite with molten iron produced by an aluminothermic reaction

Glass Physics and Chemistry, 2007
The problems regarding the use of hematite-based ceramics as sacrificial ceramic materials are considered. The interaction of hematite with an iron melt produced by a self-propagating high-temperature reaction is investigated. It is revealed that the hematite-based ceramic material containing activating additives of 3d element oxides is wet by the iron

Preparation of Al-Sc Master Alloy by Aluminothermic Reaction with Special Molten Salt

2012
Al-Sc master alloy is prepared by aluminothermic reaction with a kind of special molten salt under the normal atmospheric condition. To achieve larger Sc recovery rate, the composition and pretreatment of the molten salt are studied. The optimum molten salt is obtained by melting together Sc2O3, NaF, KCl, NaCl, ScF3 and Na3AlF6 mixture under a mass ...

Effects of Al content on formation of TaC, Ta2C, and Ta2AlC by combustion synthesis with aluminothermic reactions

Ceramics International, 2017
Abstract Fabrication of TaC–, Ta 2 C–, and Ta 2 AlC–Al 2 O 3 composites was conducted by incorporating aluminothermic reduction of Ta 2 O 5 into self-propagating high-temperature synthesis (SHS). Starting materials of this study included Ta 2 O 5 , Al, Al 4 C 3 , and carbon black powders.

Exploring the high-temperature thermoelectric performance of Al-doped ZnO ceramics prepared by in-situ aluminothermic reactions

2021
Zinc oxide (ZnO) is a highly versatile and well-known material, widely used for its useful optoelectronic, catalytic, and photochemical properties [1]. In the search for alternative energy sources, ZnO-based ceramics emerge as promising materials for high-temperature thermoelectric (TE) applications [2], capable of direct conversion of (waste) heat to ...
