ABSTRACT Fibrous calcium sulfate is produced by autoclaving a dilute aqueous suspension of gypsum, at a temperature between the minimum fiber forming temperature and about 20°C above, in the presence of a dispersing agent to provide for discrete whisker crystal development and protecting the whisker crystals from destruction or conversion to a different physical or chemical form until they have been stabilized by calcining at a temperature in excess of 500°C. The process of the present invention provides a fibrous calcium sulfate product of markedly improved dispersibility, longer fibers and with more complete conversion of the calcium sulfate fibers than the prior art processes. The fibrous calcium product is useful as a reinforcing agent for either organic or inorganic matrix materials. bm:
