[0048] Compositions for ceramic fiber production were prepared with the ingredients and contents listed in Table 1 below by a charge-type melting process using a three-phase electrode, and then ceramic fibers were produced from the composition by a conventional process for producing RCF inorganic fibers. Comparative Example 1 represents the composition used for the production of conventional RCF, Comparative Examples 2, 4 and 5 represent the compositions used for the test, and Comparative Example 3 is the composition used for the production of products used at 1100°C.
[0049] For the produced ceramic fibers, the average fiber diameter, non-fiberized shot content and production volume were calculated and determined, and the results are shown in Table 1.
