Abstract

Long whiskers of calcium molybdate (CaMoO₄) were selectively grown by rapid cooling of a NaCl flux. The crystal growth of CaMoO₄ was conducted by heating a mixture of solute and flux at 900 °C for 10 h and then cooling to 500 °C at a rate of 270 °C·h^-1 or quenching in a furnace with the electric power turned off. The obtained whiskers were colorless and transparent. Transmission electron microscopy images showed that the grown whiskers were of a very good crystallinity. The major constituents were homogeneously distributed throughout the whiskers. Sodium and chlorine atoms from the flux were not detected. Whiskers grown from the solutions were up to 5.2 mm long and 7 μm in diameter. The whiskers were cylindrical in shape with average aspect ratios ranging from 150 to 750, and they elongated dominantly in the 〈110〉 directions.
