- Bulk density, porosity and thermophysical properties of the Sołtmany meteorite have been determined. The mean bulk density of the meteorite is 3.475‧103kg/m3, mean bulk density of the crust is 4.3‧103 kg/m3, grain density 3.71‧103 kg/m3, and porosity 6.4 ±} 0.4%. Mean specific heat capacity determined by DSC in temperature range between 223 and 823 K increases from 595 to 1046 J/(kg‧K), and is equal to 728 J/(kg‧K) at room temperature. Specific heat capacity of various samples is in the range 705–769 J/(kg‧K) at room temperature. Thermal capacity of Sołtmany chondrite is equal to 2.53‧106 J/(m3‧K), thermal diffusivity (1.5–1.8)‧10-6 m2/s, and thermal conductivity 3.9–4.5 W‧m–-1‧K-1at room temperature. Differential scanning calorimetry revealed two reversible phase transitions in the Sołtmany’s troilite: α/β transition at 423 K, and β/γ transition at 596.6 K.
