What Is Thermite?
An aluminizing agent is a mixture of aluminum powder and refractory metal oxide. The common aluminizing agent is a pink mixture of aluminum powder and ferric oxide powder (ratio about 1: 2.95). When ignited with an ignition agent, the reaction proceeds violently, alumina and elemental iron are obtained and released. A large amount of heat, the temperature can reach 2500 ° C, and emits a dazzling light, which can melt the generated iron. The aluminothermic agent is an important component of the aluminothermic reaction, which plays an important role in high-temperature outdoor operations such as rail welding. Can be used to initiate some reactions that require high temperatures.
- Aluminizing agent is put
- German chemist Hans Goldschmidt invented the aluminotherm in 1893 and applied for it two years later
- The aluminothermic reaction needs high temperature to initiate, you can insert a magnesium bar on the mixture powder to do
- Iron oxide / aluminum most commonly used in aluminizing agents, [3-5]
- The heat released during the aluminothermic reaction can cause high-melting metals to melt and flow out, so the aluminothermic method is widely used in welding rescue projects,
- 1.Metal replacement
- 2.Welding metal
- 3.Military weapons such as aluminous bombs can be made.
- 4.Fuel
