- Growth habits of ZCTC been investigated photographically by means of micro-crystallization method, and bulk crystals with dimensions of 51Â ÃÂ 15Â ÃÂ 12 and 28Â ÃÂ 13Â ÃÂ 12Â mm3 were obtained by the solvent-evaporation method.
- The two-dimensional nucleation growth mechanism and crystal twinning defect of ZCTC crystal were discovered for the first time.
- The relative dielectric constants and elastic compliance constants were determined. Meanwhile first-principles calculation was used to calculate elastic constants.
- The thermal diffusivities and thermal conductivities were obtained.
Bulk single crystals of zinc cadmium thiocyanate, ZnCd(SCN)4 (ZCTC) with dimensions of 51Â ÃÂ 15Â ÃÂ 12 and 28Â ÃÂ 13Â ÃÂ 12Â mm3 have been obtained. Growth habits were investigated, two-dimensional nucleation growth mechanism and crystal twinning defect were observed from the as-grown crystals. The thermal diffusivities were measured, and then thermal conductivities were calculated with values decreasing from 1.3683 to 0.8739Â Wâ mâ1â Kâ1 and 0.8496 to 0.5356Â Wâ mâ1â Kâ1 as the temperature increasing from 303 to 423Â K, along the a- and c-directions, respectively. The relative dielectric constants and elastic compliance constants at room temperature were determined. Meanwhile, first-principles calculation was used to calculate elastic constants.
