Wpływ domieszek $La_2O_3$ na własności elektryczne niobianu sodu $NaNbO_3$

Abstract

The temperature changes of electric conductivity and of electric permittivity were investigated for the $NaNbO_3$ and $NaNbO_3$ + /0,1%, 0,2%, 0,25%, 0,3%, 0,4%, 0,5% and 1% mol $La_2O_3$/ ceramics. Obtained data were used to determine amount of $La_2O_3$ giving optimal value of conductivity.
