Enhanced Slag Formation For Copper-Containing Gas Generants

Enhanced Slag Formation For Copper-Containing Gas Generants

Gas generants comprising copper are provided that have improved slagging ability. In certain aspects, the gas generants include a fuel, an oxidizer comprising basic copper nitrate, and a large particle size endothermic slag-forming component, such as aluminum hydroxide (Al(OH)3). The gas generants m...

Zusammenfassung:Gas generants comprising copper are provided that have improved slagging ability. In certain aspects, the gas generants include a fuel, an oxidizer comprising basic copper nitrate, and a large particle size endothermic slag-forming component, such as aluminum hydroxide (Al(OH)3). The gas generants may be cool burning, e.g., having a maximum flame temperature at combustion (Tc)≤about 1,900K (1,627° C.). The disclosure also provides methods of enhancing slag formation for a gas generant composition that comprises copper. Such methods enhance slag formation during combustion of the gas generant composition by at least 50%.
