Zmiany temperaturowe współczynnika rozszerzalności liniowej $NaNbO_3$

Abstract

The operation principle of a dilatometer is described. The temperature changes of the coefficient of linear expansion were measured in temperature range between minus 196°C and plus 740°C. Linear expansion coefficient changes at following temperature values: -6°C, 280°C, 322°C, 470°C, 640°C.
