Formation and Conversion of Inorganic Fine Particles in the Atmosphere
The interaction of water and ammonia in the gas phase with sulphuric acid droplets has been described in terms of a phase diagram. The behaviour of nitric and hydrochloric acid in this system has briefly been mentioned. The apparent non equilibrium state between the composition of graphite rich particles and precipitation at ground level has been discussed. The difficulty of obtaining reliable data concerning coarse particles has been pointed out. An example of their reactivity as a function of particle size has been given.
