ABSTRACT:
The properties of mineral fibres comprising silicon, magnesium, calcium, iron, aluminium and oxygen atoms are improved by exposure to a heat treatment under oxidising conditions which causes migration of MgO, thereby creating an outer layer with increased concentrations of MgO. Batts and other fibrous products containing the fibres have increased resistance to shrinkage and sintering.
