Title:
INORGANIC FIBROUS MOLDED REFRACTORY ARTICLE, METHOD FOR PRODUCING INORGANIC FIBROUS MOLDED REFRACTORY ARTICLE, AND INORGANIC FIBROUS UNSHAPED REFRACTORY COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2011/083696
Kind Code:
A1
Abstract:
Disclosed is an inorganic fibrous molded refractory article having high biosolubility, which is capable of achieving desired heat resistance without containing ceramic fibers such as alumina silicate fibers, alumina powder and silica powder and is reduced in the production cost and the production price. Specifically disclosed is an inorganic fibrous molded refractory article which is characterized by being formed from a material that contains 2-95% by mass of biosoluble inorganic fibers having a solubility in physiological saline at 40˚C of not less than 1% by mass, 2-95% by mass of an inorganic powder having a needle-like crystal structure and 3-32% by mass of a binder. More specifically, the inorganic powder having a needle-like crystal structure has an average length of 1-3,000 μm and an aspect ratio of 1-1,000.
