  • Process for depositing a silica coating on a metal surface
    Patent number: 4564537
    Abstract: Silica may be deposited on metal surfaces e.g. on heat exchanger surfaces to reduce undesirable deposits by the following aqueous process. Finely divided moist silicic acid of defined particle size is mixed with hot (e.g. at least 98.5.degree. C.) pure water for not more than 1 hour. The mixture is subjected to depolymerization by heating at specified pH so as to depolymerize substantially all the silica. The resulting aqueous silica is then passed over the surface to be coated at temperature above 80.degree. C. so as to deposit a hard bound silica coating.
