Objective: Analyzes the quality of commercialized magnetitum

which offer the basic materials for setting up the scientific and feasible quality standards. Method: 27 samples were collected from different areas

which were analyzed through the appearance shape

internal structure and the iron content. Result: The appearance shape of commercialized Magnetitum was difference. The main content of the Magnetitum was magnetite. The iron content 9 samples in all 19 fresh samples was more than 50% and only 3 samples in all 8 processed samples was more than 45%. Conclusion: On the market at present

the qualified commercialized magnetitum was low. In order to ensure the safe and effective in clinical medication and control the quality

its necessary to improve the cleaning technology of magnet materials.
