Description
Manganese is a chemical element in the periodic table of elements, with symbol Mn and atomic number 25.
Manganese compounds have been used by humans for thousands of years. Paints with manganese pigments made from manganese dioxide can be traced back 17,000 years. The Romans and Egyptians used manganese compounds to colour and decolour glass. The Spartans used iron ore containing manganese to make their weapons. The fact that the high quality of the weapons was based on an iron-manganese alloy must be regarded as speculation.

* This is a recommendation based on our experience with these materials in our sputter guns. Rates are based on unbonded targets and are material specific. Bonded targets should be operated at lower power to avoid bonding failure. Bonded targets should be operated at 20 watts/square inch or less depending on the material.
