All the lots of powders obtained were analysed by X-ray, specific surface area and magnetic properties. It was established that a specific surface area depends on the temperature ant a time of isothermal exposure. There were a conclusion that the biggest specific surface area (58,2 m2/g) can be obtained for complex systems under decomposition/reduction of metals from mixture of oxalate. Increasing the temperature and time of isothermal exposure the specific surface area of iron oxydes decomposited/reduced at the temperatures of 400, 450 оС decreased from 46,6 m2/g to 40, 30 m2/g at 475, 500, 600 і 650 оС .
