Abstract
Calcium sulphate dihydrate nanocrystals of 25–100 nm width have been synthesized in 100% purity and yield by means of a method—the cryo-vacuum process—consisting of rapid freezing of quasi-saturated solutions and subsequent vacuum assisted sublimation of water. Transmission electron microscopy reveals both curled nano-lamellae and smaller, irregular particles; electron diffraction patterns demonstrated that the particles are crystalline. This is a very powerful method for the ‘clean’ synthesis of moderately and completely water-soluble inorganic materials.
