<p>A method of forming fibres comprising SrO, Al2O3, and a fibre forming additive, the method comprising the steps of either: a) mixing: i) a compound of strontium which on heating loses a volatile component, ii) Al2O3, and iii) a fibre forming additive; b) calcining the mixture to remove the volatile component; c) melting the calcined mixture or: a) mixing: i) a compound of strontium which on heating loses a predominantly non-toxic volatile component, ii) Al2O3, and iii) a fibre forming additive; b) forming granules from the mixture of a sufficient size to resist ejection from a melt by outgassing; c) melting the granules and extracting the predominantly non-toxic volatile component either followed by: d) disrupting the melt to form fibres.</p> |
