INORGANIC FIBROUS MOLDED REFRACTORY ARTICLE, METHOD FOR PRODUCING INORGANIC FIBROUS MOLDED REFRACTORY ARTICLE AND INORGANIC FIBROUS UNSHAPED REFRACTORY COMPOSITION
PROBLEM TO BE SOLVED: To provide a highly bio-soluble inorganic fibrous molded refractory article which can develop desired heat resistance even without containing ceramic fibers such as aluminum silicate fibers, alumina powder and silica powder and can be provided at a reduced production cost and a reduced product cost.SOLUTION: The inorganic fibrous molded refractory article is composed of material including: 27 to 63 mass% of bio-soluble inorganic fibers having a dissolution ratio in a physiological saline at 40°C of 1 mass % or more; 27 to 63 mass% of inorganic powder having one or more kinds of needle-like crystal structures selected from wollastonite powder, sepiolite powder and attapulgite powder; and 3 to 18 mass% of a binder. The inorganic fibrous molded refractory article does not include alumina powder and silica powder, and includes 90 mass% or more in total of the bio-soluble inorganic fibers, inorganic powder having the needle-like crystal structure and binder.
【課題】アルミナシリケート繊維等のセラミックファイバーや、アルミナ粉末、シリカ粉末を含有しなくても所望の耐熱性を発現するとともに、製造コストおよび製品価格を低減させた、生体溶解性の高い無機繊維質耐火成形体を提供する。【解決手段】４０℃における生理食塩水への溶解率が１質量％以上である生体溶解性無機繊維２７〜６３質量％と、ワラストナイト粉末、セピオライト粉末、アタパルジャイト粉末から選ばれる１種以上の針状結晶構造を有する無機粉末２７〜６３質量％と、バインダー３〜１８質量％とを含む材料からなり、アルミナ粉末及びシリカ粉末を含まず、前記生体溶解性無機繊維、前記針状結晶構造を有する無機粉末及び前記バインダーを合計で９０質量％以上含むことを特徴とする無機繊維質耐火成形体。【選択図】なし
