Wpływ niestechiometrii na zmiany czasowe i temperaturowe prądu depolaryzacji ceramiki niobianu sodu
(1986)
Time and temperature changes of polarisation and depolarisation currents of the $NaNbO_3$ ceramics samples assumed
to have correct stoichiometric content and of the samples $NaNbO_3$ having the excess of niobium or sodium ...
Wpływ pola magnetycznego na własności $BaTiO_3$
(1986)
Influence of the constant magnetic field on temperature changes of the dielectric constant and on the electric
conductivity of $BaTiO_3$. It was shown for this material that together with the increase of the magnetic ...

Zmiany temperaturowe współczynnika przewodnictwa ciepła niobianu sodu
(1986)
Construction of the vacuum thermostat intended for measuring the heat conductivity of ferroelectrics and its
temperature changes is presented.
The properties of $NaNbO_3$ are studied in order to apply it in building the ...
Temperature changes of the Seebeck coefficient for nonstoichiometrc $NaNbO_3$
(1988)
Dla niestechiometrycznej ceramiki niobianu sodu zbadano temperaturową zależność współczynnika Seebecka i
określono typ przewodnictwa elektrycznego. Stwierdzono, że wartość współczynnika Seebecka zależy od stopnia ...
Low frequency admittance measurements of polycrystalline sodium niobate
(1988)
Complex admittance measurements for the polycrystalline sample of sodium niobate with nonstoichiometric
composition has been carried out at very low frequencies with the help of direct phase-amplitude method. Results ...
Temperature dependence of dielectric properties of nonstoichiometric $NaNbO_3$
(1988)
Systematic studies of the dependence of dielectric and semiconducting properties on the deviation from
stoichiometry have been undertaken. A complex picture of the dependence of studied properties on the chemical ...
Antiferroelectric-paraelectric phase transformation in nonstoichiometrc $NaNbO_3$
(1988)
Admittance of polycrystalline sodium niobate synthetized with nonstoichiometric proportion of the constituent
oxides has been investigated at elevated temperatures. Basic values characterizing the AFE-PE phase
transformation ...
