Submicron CaZrO3 powder is obtained in combustion reactions (solution combustion synthesis—SCS) with glycine. It is found that SCS reduces the sintering temperature of CaZrO3 powders. The dielectric properties of calcium zirconate ceramics are studied by the electrochemical impedance method. It is shown that a ceramics of powders obtained by the SCS method has high dielectric characteristics. 相似文献

The objects of study were mixtures containing triglycerides and lower alcohols and also the products of the transesterification
of triglycerides, glycerol and fatty acid esters. The Redlich-Kwong-Soave equation of state was used as a thermodynamic model
for the phase state of the selected mixtures over wide temperature, pressure, and composition ranges. Group methods were applied
to determine the critical parameters of pure substances and their acentric factors. The parameters obtained were used to calculate
the phase diagrams and critical parameters of mixtures containing triglycerides and lower alcohols and the products of the
transesterification of triglycerides, glycerol and fatty acid esters, at various alcohol/oil ratios. The conditions of triglyceride
transesterification in various lower alcohols providing the supercritical state of reaction mixtures were selected. 相似文献

The electrosurface characteristics of titanium oxide nanoparticles synthesized by the sol-gel method are studied in relation
to the pH and concentration of solutions of sodium, potassium, barium, and lanthanum chlorides. The surface charges and electrokinetic
potentials are found, and the positions of the points of zero charge are analyzed as depending on the type and concentration
of cations. The absence of a negative region of the electrokinetic potential, which results from the superequivalent adsorption
in the Stern layer, is revealed for BaCl2 and LaCl3 solutions. 相似文献

Single-particle proton energies near the Fermi energy in 64,66,68Zn are analyzed using the mean field model with dispersive optical potential. Good agreement is obtained between the calculated
energies and experimental data. The set of parameters of the dispersive optical potential is compared with the set found for
neighboring 58,60,62,64Ni with the magic number Z = 28. 相似文献
