Abstract of Disclosure To provide a highly bio-soluble fibrous shaped refractory article which can develop desired heat resistance without containing ceramic fibers such as aluminum 5 silicate fibers, alumina powder and silica powder and can be provided at a low production cost and a low product cost. An inorganic fibrous shaped refractory article comprising 2 to 95 mass% of bio-soluble inorganic fibers having a dissolution ratio in a physiological saline at 400C of 1 mass% or more, 2 to 95 mass% of inorganic powder having a needle-like crystal 10 structure and 3 to 32 mass% of a binder, and in particular, it is an inorganic fibrous refractory article wherein the inorganic powder having the needle-like crystal structure has an average length of I to 3000 pm and an aspect ratio of 1 to 1000. |
