Biosoluble ceramic fiber composition with improved solubility in a physiological saline solution for a high temperature insulation material

摘要

The present invention relates to a biosoluble ceramic fiber composition with a superior solubility in a physiological saline solution for a high heat insulating material, and more particularly to the biosoluble ceramic fiber composition wherein the physiological saline solubility is improved by optimizing the amounts of network former (SiO2), network modifiers (CaO and MgO) and intermediates (ZrO2 and Al2O3), especially the physiological saline solubility at a high-viscosity range with a high proportion of network former (SiO2) is improved by optimizing the amounts of intermediates (ZrO2 and Al2O3); thermal and mechanical properties such as a heat resistance, a compressive strength and a restoring force are so improved as to be superior even at a high temperature by optimizing the amounts of network modifiers (CaO and MgO); and the conventional fiber forming equipments can be still employed to an economical advantage.
