Paper Abstract

Many kinds of crystals can be grown by processes in which liquid reactant solutions diffuse into pure solvent and react chemically, as follows, to form single crystals, which are relatively insoluble: A (soluble) + B (soluble) + ... = C (insoluble) + D (soluble) + We call these solute diffusion processes or diffusion processes. Three examples are (1) CaCO3 grown from aqueous solutions of CaC12 and NH4HCO3; (2) PbS, from aqueous solutions of PbCl2 and CH3CSNIH2; and (3) tetrathiofulvalenetetracyanoquinonedimethane (TTF-TCNQ), from solutions of TTF and TCNQ in acetonitrile. We chose these examples to study in experiments performed on the NASA Long Duration Exposure Facility (LDEF). All three have been grown by ground-based solute diffusion processes.
