Growth and Characterization of Novel SrB<sub>2</sub>O<sub>4</sub> Crystals
Abstrak
A new polymorph modification of SrB<sub>2</sub>O<sub>4</sub> was obtained from melt containing Sr<sub>2</sub>CO<sub>3</sub>, H<sub>3</sub>BO<sub>3</sub> and CuCl<sub>2</sub>·2H<sub>2</sub>O with a molar ratio of 2:2:1. The growth was carried out by cooling the melt from 1180 to 860 °C. The obtained material looks like a green bulk mass at the edges, of which grew transparent single crystals of SrB<sub>2</sub>O<sub>4</sub> (approximately 0.1 × 0.2 × 0.1 mm in size). The crystals were studied by scanning electron microscopy, single crystal, powder X-ray diffraction, DTA/TG and FTIR spectroscopy. The single crystal structure data of SrB<sub>2</sub>O<sub>4</sub> shows orthorhombic <i>Pna</i>2<sub>1</sub> symmetry. The structure is built up of linked BO<sub>4</sub> and BO<sub>3</sub> units and the charge is compensated by strontium cations.
