    摘要： Methods of manufacturing composites are provided, including combining dihydrate calcium sulfate whiskers, hemihydrate calcium sulfate stucco, and water to form a slurry, and setting the slurry to form a composite having a natural porosity of about 60 volume percent or greater. Composites are also provided, including dihydrate calcium sulfate whiskers and dihydrate calcium sulfate crystals, and having a natural porosity of about 60 volume percent or greater.

    摘要： Methods of making calcium sulfate whiskers are provided. In one aspect, a method includes autoclaving a slurry of calcium sulfate hemihydrate and water to form calcium sulfate hemihydrate whiskers in water and microwaving the whiskers to dewater them, wherein the microwaving is effective to prevent a majority of the whiskers from reverting to a dihydrate form. In one aspect, a method includes microwaving calcium sulfate hemihydrate whiskers to form anhydrite calcium sulfate whiskers, wherein the microwaving is effective to remove a substantial amount of chemically bound water from the whiskers.
