ABSTRACT:
Coal particles are made resistant to spontaneous combustion by coating them with silicon dioxide by a vapor deposition process in which the particles in a coating chamber are contacted at a temperature that promotes the deposition on the particles of the reaction products between silicon tetrachloride vapor and water, the coating step followed by elevating the chamber temperature to drive off water vapor and hydrochloric acid.
