Abstract:

Solid solutions of the ZrO2-CaO system with 7, 9. 6, and 20 mol % of calcium oxide are analyzed by X-ray and neutron diffraction and small-angle neutron scattering. Samples are synthesized by the sol-gel method and annealed at the temperature T = 600°C for 4 h. All samples have a tetragonal structure (P42/nmc space group). The size of crystallites is 10-20 nm. Small-angle neutron scattering curves are characterized by a peak near the momentum transfer q = 0. 5 nm-1. The existence of the peak is caused by correlation between solid nanoparticles in the samples. Density correlation functions are numerically computed from the experimental small-angle scattering cross-sections by the inverse Fourier transform. Correlation lengths, concentrations of scattering nanoparticles, and specific surface areas of the samples are determined. © 2011 Pleiades Publishing, Ltd.
