Melt-Formed Inorganic Fibres

Abstract

A needled blanket is provided comprising melt-formed inorganic fibres having an overall composition in weight percent SiO2: 47 to 65% Al2O3: 35 to 53% the blanket having a shot content, of shot >45 µm, of less than 51 wt%, a specific surface area (BET) > 0.25 m2.g-1. also disclosed are fibres for producing such blankets, and self-supporting products made from such fibres.

Dependencies are inferred from the claim text.
