The synthesis of fluor-analogues of natural asbestos by unidirectional crystallisation

Abstract

A previous letter1 reported a novel technique for the preparation of aligned fibrous crystals by drawing filaments of glass through a supported molten zone. The method was subsequently modified so that the filament is drawn from a melt through an orifice in the base of a conical platinum crucible2. This technique has now been successfully applied to the preparation of filaments consisting of aligned fibres of fluoramphiboles, synthetic analogues of natural amphiboles with isomorphous replacement of hydroxyl by fluorine. These aligned fibrous crystals can be compared with natural amphibole asbestos.
