摘要：
Commercial gamma-Fe2O3 ferro-powders obtained by the sulphate technology, have been compared by means of thermal analysis. Depending on the technology, each type of gamma-Fe2O3 Was found to be characterized by certain thermal transformation sequence. Thermal analysis and data systematisation allowed to find criteria for the qualification of gamma-Fe2O3 particles. LKN ferropowders were found to have more disbalanced surface properties and chemical composition than PERK and GX ferro-powders.
