DESCRIPTION
Chemical Manganese Dioxide (CMD) consists of a precipitated MnO2 (Mn content approx 60%, MnO2 approx. 90%), which is produced using different processes. It is a brown-black powder remains, which is practically insoluble in water. Even with cold sulfuric or nitric acid, there is virtually no reaction. In the electronics industry, CMD can be found in varistors, thermistors and capacitors, among other things. In addition, also in ferrites and as an oxygen supplier in oxidizing reactions. It is also used as an inorganic pigment as well as in the glass industry.
