Beschreibung
Zusammenfassung:The present invention relates to a composition for preparing ceramic fiber and a biosoluble ceramic fiber prepared therefrom for heat insulating material at high temperature, more specifically, a composition for preparing ceramic fiber comprising SiO2 as a network-forming oxide, CaO and MgO as modifier oxides, and ZrO2, Al2O3 and B2O3 as intermediate oxides with appropriate ratios, which improves the solubility of the ceramic fiber in artificial body fluid; shows good thermal/mechanical properties such as heat resistance, high-temperature viscosity, compressive strength and restoration when used at a high temperature of 1260 ?; and provides an economic effect that a ceramic fiber can be prepared easily by using the existing facilities, and a biosoluble ceramic fiber prepared therefrom for heat insulating material at high temperature.
