ABSTRACT:
A non-settling refractory mortar is provided, which includes 100 mass % of a ceramic powder such as cordierite, mullite, alumina, or silicon carbide, 0.5 to 1.5 mass % of a clay mineral, and a colloidal oxide solution, in which the Ca content in the total solid component is defined at 0.01 to 0.5 mass % as converted to oxide so as to be provided with a thixotropic property. As a result, the coating performance is not lowered if stored for a long period after kneading, the dimension change rate after coating is small, and cracks or gaps are not formed on the coat surface. The median diameter of ceramic powder is preferred to be 10 to 50 μm, and in order to reduce the dimension change rate after coating, the content of particles of 0.1 to 5 μm in ceramic powder is desired to be 1 to 20%.
