Today, ferromanganese can be still efficiently produced in a blast furnace, but, even in this case, electric arc furnace are spreading. More commonly, ferroalloys are produced by carbothermic reactions , involving reduction of oxides with carbon (as coke) in the presence of iron.
Ferrophosphorus is a ferroalloy, an alloy of iron and phosphorus. It contains high proportion of iron phosphides, Fe 2 P and Fe 3 P. Its CAS number is 8049-19-2. The usual grades contain either 18 or 25% of phosphorus. [1] It is a gray solid material with melting point between 1050-1100 °C. It may liberate phosphine in contact with water. Very ...
Ferromanganese metal, note mirror-like sheen responsible for German name spiegel. Ferromanganese is an alloy of iron and manganese, with other elements such as silicon, carbon, sulfur, nitrogen and phosphorus. [1]
The history of ferrous metallurgy in the Indian subcontinent began in the 2nd millennium BC. Archaeological sites in the Gangetic plains have yielded iron implements dated between 1800 and 1200 BC. [24] By the early 13th century BC, iron smelting was practiced on a large scale in India. [24]

Ferroaluminum (FeAl) is a ferroalloy, consisting of iron and aluminium.The metal usually consists of 40% to 60% aluminium. Applications of ferroaluminum include the deoxidation of steel, [1] hardfacing applications, reducing agent, thermite reactions, AlNiCo magnets, and alloying additions to welding wires and fluxes.

Discovered in 1874, world ferrotungsten production today is dominated by China, which in 2008 exported 4,835 t (gross weight) of the alloy. Ferrotungsten is relatively expensive, with the prices around $31–44 per kilogram of contained tungsten. [4]
In 1998, the Ukrainian Association of Ferroalloy Manufacturers (UkrFA) was established, which included the plant. [5] In September 2005, the plant began production of ferrosilicoaluminum (composed of 15–20% aluminum and 50–70% silicon), which was mastered on the furnace No. 1, which previously produced ferrosilicon.
