Influence of CrO_3 Additive on the Thermite Reaction Procedure in Fe_2O_3+Al System
Source abstract
Abstract
A hercynite-free ceramic lined steel pipe was fabricated by the self-propagating high-temperature synthesis gravitational-thermite process(SHS G-T Process). The sequence of some reactions which are possible to take place in the aluminothermic system was determined by ther-modynamic analysis, i.e. CrO3Fe2O3Fe3O4 FeOFeAl2O4 Cr2O3. The results show that in Fe2O3+Al system CrO3 reacts with Al in two steps. This gives the possibility of elimination of FeAl2O4 phase, which is more reactive than Cr2O3.
