Hydrazine is an inorganic compound with the chemical formula N2H4 (also written H2NNH2), called diamidogen, archaically. A simple pnictogen hydride, it is a colorless flammable liquid with an ammonia-like odour. Hydrazine is highly toxic and dangerously unstable unless handled in solution as e.g., hydrazine hydrate (NH2NH2 · xH2O ). As of 2015, the world hydrazine hydrate market amounted to $350 million.
East india chemical is Hypochlorous acid (HClO) is a weak acid that forms when chlorine dissolves in water, and itself partially dissociates, forming hypochlorite, ClO−. HClO and ClO− are oxidizers, and the primary disinfection agents of chlorine solutions. HClO cannot be isolated from these solutions due to rapid equilibration with its precursor. Sodium hypochlorite (NaClO) and calcium hypochlorite (Ca(ClO)2), are bleaches, deodorants, and disinfectants.
Ultrasonic and megasonic cleaners are used in varied applications to clean substrate surfaces. In a typical assembly, a cleaning system includes a tank that holds a fluid medium such as an aqueous solution, which generally includes additives such as surfactants and detergents that enhance the cleaning performance of the system. Lately, more distinctive means of delivery have been utilized, particularly for single wafer applications. In one example, megasonics is diverted into a stream of fluid that impacts the substrate surface.
