ALKALI-RESISTANT NON-CRYSTALLINE INORGANIC COMPOSITION AND FIBER THEREOF
[Object] A high value-added material having excellent alkali resistance is developed by effectively utilizing waste material discharged from coal-fired power plants and copper slag discharged from copper smelters.[Solution] With regard to a non-crystalline inorganic composition containing silica (SiO2), iron oxide (Fe2O3), alumina (Al2O3), and calcium oxide (CaO) as main components, when i) a total content of silica, alumina, and calcium oxide is set to be 50% by mass or more and 75% by mass or less; ii) a content of iron oxide is set to be 26% by mass or more and less than 40% by mass; and iii) iron oxide is derived from a non-crystalline raw material, an inorganic composition that can be melt-spun and has excellent alkali resistance is obtained. In this inorganic composition, most of the raw materials can be derived from coal ash and copper slag.
