Abstract
A protective refractory metal oxide coating of 3Al.sub.2 O.sub.3.2SiO.sub.2 or 3B.sub.2 O.sub.3.2SiO.sub.2 is coated on the internal surface of a vessel by low pressure plasma induced chemical reactions. The source of the SiO.sub.2 required for the reaction can either be from the internal surface of the vessel (e.g., glass, quartz) or it can be introduced into the vessel.
