There are several aspects of chemical reactions associated with microparticles that are of considerable interest. Among these are homogeneous gas-phase reactions which produce clusters that grow and coagulate to form nanometer or larger size particles, reactions between reactive gases and pre-existing droplets and solid particles, and precipitation reactions that occur in solutions to produce microcrystals. An elementary example of a gas phase process that produces particulate matter is the reaction between vapors of ammonia and hydrochloric acid to form ammonium chloride smokes when they come in contact.
