What is alumino-thermic reduction?
Asked by | 19th Mar, 2008, 04:45: PM
it is a process to weld broken piecec of iron rails girders etc it is also called thermit or gokdschmidt's reaction .
a mix of 3 parts of iron oxide n 1 part of Al powder called thermit i staken in a crucible with a hole at base . this cricible is placed over broken part n thermot is ignited by mix of KClO3 n Mg using a fuse of burning Mg
vigrous reac occur n temp of3000 C is acieved molte iron from ironoxide n Al drops over broken gap n fills it

- Que:- How is the aluminium metal extracted? (In the bauxite ore it occures as hydrated aluminium oxide ,so also explain the steps we need to follow before electrolytic reduction)
- Both Al2O3.2 H2O (bauxite) and Na3AlF6(Cryolite) contain aluminium metal in them. But bauxite is used to extract aluminium metal but not Cryolite. Why?
- what is calcination?
- What is rusting
- what is metallurgy
- What are the uses of bronze and brass alloys? (State with reason)
- Difference between electrolytic reduction and electrolytic refining.
- Why does lmpure copper dissolve but not pure copper in acidified copper sulphate solution during electrolytic refining of copper
- By which process metal can be obtained from metal oxide?
- describe the use of aluminium asc reducing agent for reduction of metal oxides .. give the equations involved
