<p>PURPOSE: A saline-soluble ceramic fiber composition is provided to produce a ceramic fiber with the improved high temperature physical property and biodegradation property. CONSTITUTION: A saline-soluble ceramic fiber composition for a high temperature heat insulating material contains 58~67wt% of SiO2, 26~34wt% of CaO, 2~8wt% of MgO, 0~1wt% of Al2O3, 0~5wt% of B2O3, 0~3wt% of Na2O and K2O, and less than 1wt% of impurity selected from TiO2 or Fe2O3. The ceramic fiber composition additionally contains 0.1~5wt% of mixture including B2O3, Na2O, and K2O. The ceramic fiber composition is marked with general formula 1.</p> |
