aluminothermic reaction

In compositions intended for production of metal by aluminothermic reaction, these effects can be counteracted.

This oxide is reduced to the metal by the aluminothermic reaction or reduction with carbon in a blast furnace.

Aluminothermic reactions are exothermic chemical reactions using aluminium as the reducing agent at high temperature.

Barium peroxide can be used as a catalyst to start an aluminothermic reaction when welding rail tracks together.

The chemical reaction that produces the heat is an aluminothermic reaction between aluminium powder and a metal oxide.

The aluminothermic reaction is also used for the production of most of the ferroalloys, for example ferroniobium from niobium pentoxide.

In the process involving the aluminothermic reaction a mixture of iron oxide and niobium oxide is reacted with aluminium:

A thermite reaction, when used to purify the ores of some metals, is called the thermite process, or aluminothermic reaction.

The dichromate is converted to the chromium(III) oxide by reduction with carbon and then reduced in an aluminothermic reaction to chromium.

This oxide is mixed with iron oxide and aluminium and is reduced in an aluminothermic reaction to niobium and iron.

A thermite reaction is a type of aluminothermic reaction in which aluminium metal is oxidized by the oxide of another metal, most commonly iron oxide.

Chromium metal and ferrochromium alloy are commercially produced from chromite by silicothermic or aluminothermic reactions, or by roasting and leaching processes.

Pure molybdenum is produced by reduction of the oxide with hydrogen, while the molybdenum for steel production is reduced by the aluminothermic reaction with addition of iron to produce ferromolybdenum.

For the production of ferrochromium, the chromite ore (FeCrO) is reduced in large scale in electric arc furnace or in smaller smelters with either aluminium or silicon in an aluminothermic reaction.

For the production of ferrochromium the chromite ore (FeCr2O4) is reduced with either aluminium or silicon in a aluminothermic reaction and for the production of pure chromium the iron has to be separated from the chromium in a two step roasting and leaching process.
