Low valence manganese oxide has high activity to Oxygen (O2). It can react together with O2 and generate high valence oxide under normal temperature and pressure, so as to make the remnant O2 in the gas not more than 0.1×10-6 V/V. Its main features are: Comprehensive utilities which can be applied in many kinds of gas deoxidizing; High mechanical strength which can not be pulverized thus lose in large scale industrial production; Many times reactivation with the stable activity; Long useful time and so on.
