It is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels. It improves strength, workability, and resistance to wear. Manganese oxide is used as an oxidising agent; as a rubber additive; and in glass making, fertilisers, and ceramics. Manganese sulfate can be used as a fungicide.
As a result, the remaining slag has a concentration of 30% to 50% of the manganese. This is then reprocessed with quartzite to make silicomanganese alloys. The resultant discarded slag has a manganese content of less than 5%, increasing the yield. As a result, this method is used more often in industry.
Selenium, like manganese, can be used in small concentrations to decolorize glass, or in higher concentrations to impart a reddish color, caused by selenium nanoparticles dispersed in glass. It is a very important agent to make pink and red glass. When used together with cadmium sulfide, [9] it yields a brilliant red color known as "Selenium Ruby".
Manganese is a chemical element with the symbol Mn and atomic number of 25. It is found as the free element in nature (often in combination with iron), and in many minerals. The free element is a metal with important industrial metal alloy uses. Manganese ions are variously colored, and are used industrially as pigments and as
Raw umber (PBr7): a natural clay pigment consisting of iron oxide, manganese oxide and aluminum oxide: Fe 2 O 3 + MnO 2 + n H 2 O + SiO 2 + Al 2 O 3. When calcined (heated) it is referred to as burnt umber and has more intense colors. Raw sienna (PBr7): a naturally occurring yellow-brown pigment from limonite clay. Used in art since prehistoric ...
The nickel content of individual Chinese products varied from about 1.6% to as much as 80%, depending upon customer end use. [2] In the United States, the steel industry accounted for virtually all the ferronickel consumed in 2008, with more than 98% used in stainless and heat-resistant steels; no ferronickel was produced in the US in 2008.

The eutectic, between aluminium and Al 6 Mn is 1.3% manganese and 660 °C, while pure aluminium melts at 660.2 °C. Values of 1.8% and 657 °C or 658 °C can also be found in older literature. Above 710 °C, Al 4 Mn is formed with a manganese content of at least 4%. However, such high levels are not typically used. Below 510 or 511 °C, Al 12 ...
Hiduminium or R.R. alloys (2% copper, iron, nickel): used in aircraft pistons; Hydronalium (up to 12% magnesium, 1% manganese): used in shipbuilding, resists seawater corrosion; Italma (3.5% magnesium, 0.3% manganese): formerly used to make coinage of the Italian lira; Magnalium (5-50% magnesium): used in airplane bodies, ladders, pyrotechnics ...
