[en] Short note

[en] Effect of high-frequency electric field on PbTiO₃ and PbZrO₃ synthesis from oxides is investigated. It is found that high-frequency electric field application provides a considerable reduction of synthesis duration and temperature

[en] Measuring results of titanium, zireonium and hafnium temperature conductivity are presented in the range from 1000 to 2400 K, including regions of solid and liquid states near the melting points. Temperature- and thermal conductivities of these metals are detected to increase both at α-β transformations and in melting. It is established that at 500 to 700 K and higher the most kinetic and thermal properties become anomalous, that can't be explained in the framework of usual theoretical representations for transition metals. One of the most probable reason for different behaviour can be instability of HCP lattice as well as related to it an anomalously large amplitude of lattice point vibrations in the epipolar plane, which manifests in anomalous behaviour of the elastic constant, c₆₆
