Reducing atmosphere Reducing atmosphere A reducing atmosphere is an atmospheric condition in which oxidation is prevented by removal of oxygen and other oxidizing gases or vapours, and which may contain actively reducing gases such as hydrogen, carbon monoxide, and gases such as hydrogen sulphide that would be oxidized by any present oxygen. In metal processing, a reducing atmosphere is used in annealing ovens for relaxation of metal stresses without corroding the metal. A non oxidizing gas, usually nitrogen, is used, or for more extreme conditions, hydrogen gas. A reducing atmosphere is also used to produce specific effects on ceramic wares being fired.
Endothermic gas gas in the endothermic atmosphere is combined with an additive gas including natural gas, propane (CH) or air and is then used to improve the surface chemistry work positioned in the furnace. There are two common purposes of the atmospheres in the heat treating industry: Principal Components of Endothermic Gas Generators : Chemistry of Endothermic Gas Generators: Applications of Endothermic Gas Generators: It is relatively simple to operate and maintain endothermic gas generators, however, maintenance such as the burnout process is often overlooked. Troubleshooting the Endothermic Gas Generator (Cracking at 1040°C): Endothermic gas Endothermic gas is a gas that inhibits
