Abstract
A network former and a glass modifier are formed and maintained by using basalt rock ore, and the crystallization and binding of basalt fiber are inhibited The heat-resistance property of basalt fiber is greatly improved from the conventional 750° C. to 850 or 900° C., and significant cost reduction is achieved over conventional products. Basalt fiber material having basalt rock as a raw material to which one or more kinds of oxide selected from Al2O3, SiO2, CaO, and MgO is added, and basalt fiber material having two kinds of basalt rock containing different amounts of elements as raw materials are provided.
