In structures of silicon carbide brick the leakage of molten metal or vaporous metal through breaks in joints or a crack is prevented by hot applying mortar comprising a major component of zircon and a minor component of borates or boric acid, phosphoric acid and colloidal silica to the breakages. Adhesiveness of mortar to the breakages is improved by incorporating further agalmatolite or kaolin into the mortar. |
