SUSPENSION FOR PREPARING CURRANT-CONDUCTING COAT

FIELD: electric engineering industry. ^ SUBSTANCE: invention proposes a suspension for preparing current-conducting coat that comprises sodium meta-silicate, graphite, aluminum oxide, ferric (III) oxide, strontium carbonate, potassium titanate, barium oxide and hydrochloric acid taken in the following ratio of components, wt.-%: sodium meta-silicate, 28-30; graphite, 11-15.5; aluminum oxide, 3.5-3.7; ferric (III) oxide, 3.5-3.7; strontium carbonate, 3.5-3.7; potassium titanate, 4.2-4.5; barium oxide, 1.2-1.5; hydrochloric acid, 4.9-5.1, and water, the balance. Invention provides the creature of current-conducting coat with positive temperature resistance coefficient for conferring high resistance to heat loadings to it. Invention can be used in producing film heating surfaces and electric heaters. ^ EFFECT: valuable properties of suspension. ^ 1 tbl
