Abstract

The electromeltable material is useful in metal casting for making articles and details able to contact with metal melts and for making high-temperature insulators. The following ingredients in weight parts are included in the material's composition : magnesium oxide from 1 to 35, aluminium oxide from 9 to 45, silicon dioxide from 28 to 42, silicon carbide from 0,1 to 20 and natrium silicon fluoride from 17 to 29.
