    • Abstract
  • The thermodynamics such as dissolve and melt process of nano-material is different from bulk material because of fine size and high interfacial energy of nano-material. The relations between element equilibrium solution product, melting point and size of nano-particle have been deduced. Results show that element equilibrium solution product increase and melting point drop down gradually with the decrease of nano-particle size. The change of equilibrium solution and melting point increases with the variation of nano-particle size. Calculations show that increment percent of element equilibrium solution product is 11.71% of radius 0.1nm Al 2O3 than bulk Al2O3 that 0.01% mass in liquid iron. The melting points of radius 1nm Al2O3 are respectively 1849K and 1267K in the atmosphere and liquid iron. The decrement of melt points are respectively 454K and 1036K.
