FIELD: metallurgy. SUBSTANCE: invention relates to protection of metal molds and other heated metal members of structure and equipment. Coating including metal oxide-based material, phosphate binder, boric acid, and water is distinguished with that above metal oxide-based material is dust from gas purification stage in the electrothermal silicon production and phosphate binder is an aluminophosphate material. In total, coating contains (in wt %): gas purification dust, 5-68; aluminophosphate binder, 21-51; boric acid, 0.1-6; water 10-32. EFFECT: reduced cost due to utilizing industrial waste. 3 tbl |
