THE MEASUREMENT OF THE SURFACE TENSION OF ALUMEL IN THE SOLID STATE
The paper is devoted to the measurement of the surface tension of solid alloy on the base of nickel and alumina, using as an element of thermocouple in electronics. The measurements were done by compensation zero creep method, developed for the high temperature measurements, on the polycrystalline samples of cylindrical shape. At the temperature 1600 ± 40 К for surface tension the value 150040 mJ/m <sup>2</sup>was obtained. For comparison the surface tension data of pure Ni in the solid state, so as corresponding data of surface tension of Ni in the liquid state are given.
