Single crystals of pseudo-wollastonite （α-CaSiO₃） were growth by using NaCl as flux. The experiments for growing crystals were carried out in platinum crucible by cooling slowly the fused matter from 1,200 ℃ to 800 ℃ at a rate of 3∼5 ℃/hr. The starting raw materials used have been synthesized with stoichiometric mole ratio (CaO : SiO₂=1 : 1) by solid and hydrothermal rection. The grown crystals obtained in such a method have lath-like habit elongated to b-axis. These seemed to be grown from spontaneous nuclei which were precipitated on the wall of the crucible from the supersaturated solution by slow cooling. The crystal size was measured by an optical microscope and various characteristics were also investigated by using X-ray diffractometer, electron microscope, and scanning microscope.
