HIGH TEMPERATURE RESISTANT FIBRES

摘要

Thermal insulation comprises sol-gel formed fibres comprising 10 to 99mol% of a refractory base composition, and 1 to 90mol% of a component selected from alkaline earth metal oxides, alkali metal oxides, and mixtures thereof, and wherein said alkaline earth metal oxides if present comprise one or more of calcium oxide, strontium oxide, barium oxide or a mixture thereof . The refractory base comprises SiO2 and A12O3.
