Thermodynamic Analysis of the Cu-Si-Ni-O System

摘要

The liquidus surface of the Cu_2O-SiO_2-NiO ternary phase diagram is constructed. It is shown that the peritectic reactions occur in the ternary diagram; due to them, a the existence region of nickel olivine Ni_2SiO_4 with oxide melt manifests itself. A solubility surface of components in the metal of the Cu-Si-Ni-O system for a temperature of 1200°C is constructed.
