Abstract
Bulk paint and ceramic powder systems, methods of forming same, and methods of forming a flexible ceramic coating on a metal substrate are disclosed. The systems may include a ceramic composition having between 2 to 30 weight percent of an alkali metal oxide, such as K2O, Na2O, and Li2O or mixtures thereof, between 10 to 74 weight percent SiO2, and between 23 to 79 weight percent B2O3. Additives that are nonwetting with molten metals, such as boron nitride, provide durable coatings for metal processing operations. The ceramic composition may include less than 5 weight percent additional metal oxides. The bulk paint system further may include water and a cellulosic suspension agent to form a bulk paint. The ceramic powder system may be processed to form a uniform powder. The bulk paint or uniform powder may be applied to a metal substrate, such as a ferrous metal substrate, dried, and heated to form a flexible coating on the metal substrate.
