Manganese

The chemical element manganese is an element of group VII of the secondary subgroup with atomic number 25. It is the 14th most common element on Earth, and after iron, the second heavy metal. Most common as pyrolusite (mineral) .

The simple substance manganese is a silver-white metal. Along with iron and its alloys, it belongs to ferrous metals .

Application area

Manganese is widely used in ferrous metallurgy in the form of ferromanganese. It binds the sulfur in the steel, improving its properties (making it hard and resistant to wear and impact). Such steel is used for the manufacture of ball mills, earth-moving and stone-crushing machines, armor elements, etc.

Manganese is also used to make pressure gauges. An alloy of copper - manganese is used to reduce harmful industrial noise .

Manganese compounds are used in the chemical industry. For example, such as potassium permanganate (potassium manganese) is a strong oxidizing agent and is used in the synthesis of substances .

Some types of manganese salts are also used in medicine, because. have disinfectant properties .

In the ceramic industry, manganese dioxide is used to produce brown, dark red and black glazes, as well as to make colored tiles and bricks .

Oxides of manganese, its salts and organic compounds have found significant use in the dyeing and printing industry, where they are used as oil absorbers .

Manganese dioxide is also used in vanilla production .
