The LiTaO3 powders with sub micrometer grade grain size have been synthesized successfully using a molten salt method. Lithium tantalate began to form at 400 °C reaction temperature and transformed to pure phase without residual reactants when it was processed at 500 °C for 4 h in static air. The undoped LiTaO3 ceramics with a Curie temperature about 663 °C were obtained by pressureless sintering at 1300 °C for Barbour Bedale Pas Cher 3 h. The relative dielectric Barbour Belgique constant (ɛr) increases from 50 to 375 at temperature ranging from 30 to 663 °C and then decreases quickly as the temperature increases above 663 °C. The ceramics shows a relative dielectric constant of 49.4, a dielectric loss factor (tan δ) of 0.007, a coercive field (Ec) of 28.66 kV/cm and a remnant polarization (Pr) of 32.48 μC/cm2 at room temperature.

The major objective of the present investigation is to develop empirical procedures for correcting microhardness values for the size effect. Such correction procedures can be expected to be useful in the determination of equivalent bulk hardness values in the highly strained regions just beneath worn or eroded surfaces. In this paper two empirical correction procedures were defined and their usefulness was evaluated Barbour Manteau on three single-phase materials, namely iron, Cu-2Si alloy and 7075 aluminium. It is found that the hardness subtraction method (one of the two correction procedures) predicts most accurately the equivalent bulk hardness values. Finally, the methodology for converting the corrected microhardness-depth profile beneath a Brinell indentation to an equivalent strain-depth profile is illustrated and the validity of such a procedure is demonstrated.
