Abstract
Official abstract text for this publication.
An inorganic fibrous shaped refractory article having a high bio-solubility which is capable of exhibiting a desired heat resistance without containing expensive ceramic fibers, alumina powder and silica powder can be provided at a low production cost and with a low product price. An inorganic fibrous shaped refractory article includes 2 to 95 mass % of rock wool, 2 to 95 mass % of inorganic powder having a needle-like crystal structure and 3 to 32 mass % of a binder. Preferably, in the an inorganic fibrous shaped refractory article, the inorganic powder having a needle-like crystal structure has an average length of 1 to 3000 μm and an aspect ratio of 1 to 1000, and more preferably the inorganic powder having a needle-like crystal structure is wollostonite powder or sepiolite powder.
