Bulk modulus of coarse-crystalline and nanocrystalline silver sulfides

The change in the bulk modulus of coarse-crystalline and nanocrystalline silver sulfides is determined in the temperature range 300–960 K using the experimental data on the temperature dependences of the heat capacity and the thermal expansion coefficients of these materials. The bulk modulus of the nanocrystalline silver sulfide is found to be lower in magnitude than modulus $B$ of the coarse-crystalline silver sulfide in this temperature range.
