Abstract:
1. A biodegradable ceramic fiber composition for a high-temperature thermal insulator comprising: 62.1 to 66.5% by weight SiO 26 to 34% by weight CaO; 2.9 to 6.5% by weight MgO; 0 to 1% by weight Al 0.2 to 1.1% by weight B 0.3 to 1.1% by weight sum of B 1% by weight or less sum of TiO wherein the biodegradable ceramic fiber includes a non-fibrous material (shot) at a content of less than 33% by weight, and has a linear thermal contraction coefficient of 1.4% or less (when maintained at 1100° C. for 24 hours).
