Abstract: It is intended to suppress flaming and smoking due to combustion of combustible substances in a certain-shaped joint material, while maintaining hot sealability of the certain-shaped joint material. A certain-shaped joint material for hot installation is obtained by: adding organic additives to a blend in a combined amount of 26 mass % to 50 mass %, with respect to and in addition to 100 mass % of the blend, wherein the blend comprises 50 mass % to 90 mass % of gibbsite type aluminum hydroxide raw material, 1 mass % to 9 mass % of clay, and 9 mass % to 23 mass % of graphite, with the remainder mainly composed of an additional refractory raw material; and subjecting the resulting mixture to kneading, forming and drying.
