Composition for preparing ceramic fibers and biosoluble ceramic fibers prepared therefrom for heat insulating material at high temperature
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 SiO 2 as a network-forming oxide, CaO and MgO as modifier oxides, and ZrO 2 , Al 2 O 3 and B 2 O 3 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 heart resistance, high-temperature viscosity, compressive strength and restoration when used at a high temperature of 1260°C; 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.
