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.
