FIELD: production of adhesive and covering compositions, that have good heat-resistance and perfect resistance to wear and also long service life after hardening. SUBSTANCE: composition has two components: powder mixture composed of 20 - 70 mass shares of zirconium oxide, 1 - 10 mass shares of sodium aluminate, 0.4 - 10.5 mass shares of yttrium oxide, 9.5 - 78.6 mass shares of silicon dioxide and 12.36 - 84.55 mass shares of sodium silicate - used as binder, in which 5.0 - 50.7 mass shares of water are added. To be used as coating for ingot mould, composition is added with 2 - 17 mass shares amount of fibrous heat-resistant material. As a version, using the composition heat resistant coating is produced in the form of sheet. EFFECT: covering composition has good heat-resistance and perfect resistance to wear and long service life after hardening. 5 cl
