AB  - In this article, ytterbium and erbium oxides are used as doping materials for barium titanate (BaTiO3) materials. The amphoteric behavior of these rare-earth ions leads to the increase of dielectric permittivity and decrease of dielectric losses. BaTiO3 ceramics doped with 0.01-0.5 wt% of Yb2O3 and Er2O3 were prepared by conventional solid-state procedure and sintered at 1320°C for 4 h. In BaTiO3 doped with a low content of rare-earth ions (0.01 wt%) the grain size ranged between 10 and 25 μm. With the higher dopant concentration of 0.5 wt%, the abnormal grain growth is inhibited and the grain size ranged between 2 and 10 μm. The measurements of capacitance and dielectric losses as a function of frequency and temperature have been carried out in order to correlate the microstructure and dielectric properties of doped BaTiO 3 ceramics. The temperature dependence of the dielectric constant as a function of dopant amount has been investigated. © 2009 The American Ceramic Society.

AB  - Fine agglomerate-free spherical beta-SiC powder was synthesized from a dispersion of colloidal silica, saccharose, and boric acid, by means of an ultrasonic spray pyrolysis method, Droplets of 2.2 mu m were formed with an aerosol generator, operated at 2.5 MHz, and carried into a reaction furnace at 900 degrees C with argon, Spherical X-ray amorphous gel particles of 1.1 mu m were obtained, beta-SiC particles with a mean diameter of 0.79 mu m and spherical shape resulted when the SiC gel precursor particles were heated at 1500 degrees C in argon.
