摘要：
To provide a highly bio-soluble fibrous shaped refractory article which can develop desired heat resistance without containing ceramic fibers such as aluminum 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 40°C of 1 mass% or more, 2 to 95 mass% of inorganic powder having a needle-like crystal 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 1 to 3000 µm and an aspect ratio of 1 to 1000.
