Abstract
Asbestiform crystalline calcium sodium metaphosphate fiber is prepared by (a) forming a wet mix slurry having a composition on a dry basis equivalent to a CaO/Na.sub.2 O/P.sub.2 O.sub.5 mol percent ratio of about 24.0-34.0/12.0-18.0/50.0-60.0, with the proviso that the CaO/Na.sub.2 O mol ratio is from about 1.60 to about 2.00, (b) forming and growing product crystals of calcium sodium metaphosphate under crystal formation and growth conditions between the solid phase of the wet mix slurry and substrate crystals of calcium sodium metaphosphate, and (c) fiberizing the product crystals of calcium sodium metaphosphate.
