  • Inorganic fibre compositions
    Patent number: 9944552
    Abstract: Inorganic fibers having the composition: 10?Al2O3?50 mol %; 2?K2O?40 mol %; 30?SiO2?70 mol %; and in which SiO2+Al2O3+K2O>=80 mol % can be protected against surface crystallization of kalsilite by: including an amount of a nucleation promoting component effective to promote bulk crystallization in the glass; and/or providing on at least part of their surface, potassium scavenging materials.
    Type: Grant
