The aim of this study was to evaluate the inhibitory effect of taurine and complex magnesium taurate on the crystallization of calcium oxalate with measurement of electrical conductivity and morphology. The results of electrical conductivity research suggest that both taurine and complex magnesium taurate can inhibit the growth of calcium oxalate crystals, but the latter has much stronger capability...
Electrical dc conductivity and laser damage threshold of pure and urea doped KH2PO4 crystals are investigated. It is found that the crystals with a low electrical conductivity have a high laser damage threshold. It is shown that increase of the resistivity and the laser damage threshold of the crystals realizes by the crystal growth from urea-containing aqueous solutions. The optimum molar value of...
Single crystals of PbTiO3 (PT) and BiFeO3(BFO) were grown by a self-flux method, and the influence of lattice defects on the leakage current properties at 25degC was investigated. While PT crystals annealed in air at 700degC showed a leakage current density of the order of 10-5 A/cm2 , annealing under a high oxygen partial pressure of 35 MPa at 700degC increased the leakage current density to 10-4...
In order to completely characterize the trapping levels that may be present in the red mercuric iodide (alpha-HgI2) crystals grown (a) by hydration of the HgI2-DMSO-MeOH saturated solution, (b) by isothermal evaporation of the solvent from the HgI2-THF saturated solution and (c) by polymer controlled growth in vapor phase, the temperature dependences of the isothermal current versus time characteristics...
Large and high-quality single crystal flakes of [Ca2CoO 3]0.62[CoO2] compound were grown from Co3O4 and CaCO3 reagents with chloride flux. Typical single crystal flake size is about 5times5times0.02 mm 3. Obtained crystal flakes were consolidated by the spark plasma sintering (SPS) technique at 1100 K for 1 h. Grain alignment was checked by XRD and also was confirmed by SEM observations on the fractured...
