Atmosphere Atmosphere An atmosphere (from Modern Greek ἀτμός "(atmos)", meaning 'vapour', and σφαῖρα "(sphaira)", meaning 'sphere') is a layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body. An atmosphere is more likely to be retained if the gravity it is subject to is high and the temperature of the atmosphere is low. The atmosphere of Earth is composed of nitrogen (about 78%), oxygen (about 21%), argon (about 0.9%) , carbon dioxide (0.03%) and other gases in trace amounts. Oxygen is used by most organisms
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
