Abstract: The Gibbs free energy and critical reduction temperature of vacuum silicothermic reduction producing metallic strontium were calculated and analyzed by thermodynamics.
The formation of the skin layer agrees with the spinodal decomposition (SD) mechanism, and the thermodynamic factor plays the leading role in this process.
Acid intensity of hydrosulfuric acid and stepwise ionization balance were discussed by the use of thermodynamic principle, which are helpful to inorganic chemistry teaching.
The expansion mechanism of hydroxide expanding phase for oil well cement slurry are discussed on the basis of principle of chemical thermodynamics and topochemical reaction model.
Based on the principle of thermodynamics, the authors have made much calculation of the thermal effect caused from oxidation and generation of monodrome alloys and slag.
According to the engineering thermodynamic theory,the inflating work and ebulliency work exerted by the materials composed of liquid,vapour and gas during the adiabatic process are calculated.
It is studied further that the dissolubility of the bismuthous sulfide in the solutions of the non-oxidative strong acid through the experiment by means of chemical thermodynamics.
It Is necessary to include as a heat source In the thermodynamic energy equation at erm which represems the timerate of release of the latent heat of condensation of water vapor.
