Abstract
Provided are inorganic fibers containing calcium and alumina as the major fiber components. According to certain embodiments, the inorganic fibers containing calcia and alumina are provided with a coating of a phosphorous containing compound on at least a portion of the fiber surfaces. Also provided are methods of preparing the coated and non-coated inorganic fibers and of thermally insulating articles using thermal insulation comprising the inorganic fibers.
Claims26
A low shrinkage, high temperature resistant vitreous inorganic fiber having a use temperature of 1100° C. or greater, wherein at least about 90 weight percent of said fiber comprises the fiberization product of about 35 to about 50 weight percent calcia, about 50 to about 65 weight percent alumina and about 10 weight percent or less silica impurity, and wherein at least a portion of the fiber surface is coated with a phosphorous containing compound coating.
A low shrinkage, high temperature resistant vitreous inorganic fiber having a use temperature of 1100° C. or greater, wherein at least 90 weight percent of said fiber comprises the fiberization product of about greater than 50 to about 80 weight percent calcia, about 20 to less than 50 weight percent alumina and about 10 weight percent or less silica impurity, and wherein at least a portion of the fiber surface is coated with a phosphorous containing compound coating.
