Abstract (en)
[origin: WO0076929A1] Man-made vitreous fibres having a composition which contains at least 14 % Al2O3 are produced by melting a mineral charge which includes briquettes and fiberising the melt. In the process the briquettes comprise particulate alumina-containing material having size at least 90 wt. % below 700 mu m, Al2O3 content of at least 50 wt. % and at least 20 %, preferably at least 25 %, porosity provided by pores of diameter below 1 mu m, measured by mercury porosimetry. Briquettes and processes for producing them are also disclosed.
