The isoelectric point of BaTiO3
Journal of the European Ceramic Society, 2000Abstract The value of the isoelectric point (IEP) of BaTiO 3 is highly significant for the development of a fully rational basis for the successful processing of BaTiO 3 powder by aqueous routes. We report here experimental evidence that the true IEP value for BaTiO 3 is in the neutral pH range (6–7).

Positron annihilation in BaTiO3
Physics Letters A, 1973Abstract The angular correlation of 2 γ-annihilation radiation has been measured in barium titanate single crystals. The effect on the angular correlation of the ferroelectricity in BaTiO 3 was not detected.

BaTiO3 (BTO), is a well-known and widely investigated dielectric material. It is mainly used in capacitors due to its high dielectric constant. The dielectric properties of BTO are controlled by purity and microstructure which are dependent on the methods of preparation.

Barium titanate have the valuable electrophisical properties but at heating in vacuum to 600??C BaTiO3 loses the oxygen and its properties varieties. It restricts using of standard metallization and brazing technologies for BaTiO3-ceramic so the technology of BaTiO3-ceramic metallization and soldering at lower temperatures was the aim of present study.

The complex research of the contact interaction and wetting of BaTiO3 - perovskite ceramics by metal melts is carried out. Two states of barium titanate were studied: 1. semiconducting BaTiO3???x - with oxygen defect. The experiments in vacuum for 13 pure metals and for Ti-containing alloys Cu???Sn???Ti, Cu???Ga???Ti and Ag???Cu???Ti are executed.

Positron annihilation in BaTiO3
Physics Letters A, 1978Abstract The spectra of positron lifetime and the Doppler-broadened annihilation gamma-line were measured for barium titanate monocrystals. In the polar and nonpolar phases the positrons are unable to form bound states like positronium in barium titanate.

Two kinds of mounds or hillocks have been found on BaTiO3 single crystals after etching. Rounded, flat-topped hillocks were found after etching with 1% HF for 30 sec at room temperature. These hillocks were found where a 180° domain wall had been left for several days and had been removed shortly before etching.
