Abstract

Data on volumetric changes of HgTe during melting and heating the melt were obtained by means of the gamma array attenuation technique. Negative volumetric effect has been established upon HgTe melting. The baric coefficient value of melting temperature dT/dP calculated by the Clapeyron-Clausius equation is compared with the same value obtained onthe (p-T) diagram of the Hg-Te system. The dependence density versus on temperature for liquid HgTe increases from its melting point at 943K to maximum value at 1023 K and than normal thermal expansion established. These anomalous changes of density in liquid HgTe could be explained on the basis of the ''after-melting'' effect and fully describedin terms of the ideal associated solution model assuming HgTe and Hg2Te3 associates.
