Antimony Selenide

Single crystals of antimony selenide were grown from melt by the Bridgman Stockbarger method. X-ray powder diffraction analysis was carried out to determine the lattice parameters of the grown samples.The morphology and chemical analysis of cleavage planes were investigated using SEM and EDAX. The microhardness studies were done by using a Vickers hardness tester. The correlation of energy gap and microhardness has also been investigated.

Perovskite Type

A new method for synthesizing double oxides of the ilmenite and perovskite type via aquafluoro-complexes MII(H2O)xAIVF6 has now successfully been applied to dilute solid solutions of iron (II) magnesiumtitanates FexMg1-xTiO3.Chemical analysis and X-ray powder diffraction analysis of lattice spacing shifts of different compositions warrant the conclusion that random solid solutions of mixed double oxides can be obtained by the chosen method, with the special advantages of stoichiometry and lower reaction temperatures than in previously described methods.

Float Zone

A single crystal of Mg2TiO4 was grown by the travelling solvent float zone (TSFZ) method. The lattice parameter a = 0.8444(8) nm was determined by X-ray powder diffraction analysis. The optical properties of the Mg2TiO4 single crystals were studied using spectroscopic ellipsometry. The obtained results are discussed and compared with published data.

Vertical Bridgman

Pb1-xMnxTe crystals were grown by the vertical Bridgman method. Their structural properties were observed both by optical microscopy after chemical polishing and ething, and by X-ray powder diffraction analysis. A solution of 5 vol. % Br2 in HBr at room temperatur, for an exposure of 2 min was determined for chemical polishing. Asolution of 20 g KOH in 1 ml H2O2, 2 ml glycerol (C3H8O3), and 20 ml H2O at room temperature for an exposure for 6 min was found to be a suitable etching solution. The obtained results are discussed and compared with published data.

Thermal Stability Of

Cobalt(II) and zinc(II) complexes of ethyl carbazate (ECZ), [Co(ECZ)3](NO3)2 and [Zn(ECZ)3] (NO3)2, were synthesized. Single crystals of these two compounds were grown from aqueous solutions using a slow evaporation method. Their structures have been determined by X-ray diffraction analysis. Both of them are monoclinic with space group P21/n. The complexes are further characterized by element analysis and IR measurements. Their thermal stabilities are studied by using TG-DTG, DSC techniques. When heated to 350 °C, only metal oxide was left for both complexes.
