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.

Heme iron in animals is from blood and heme-containing proteins in meat and mitochondria, whereas in plants, heme iron is present in mitochondria in all cells that use oxygen for respiration. Like most mineral nutrients, the majority of the iron absorbed from digested food or supplements is absorbed in the duodenum by enterocytes of the ...
Iron aluminides are intermetallic compounds of iron and aluminium - they typically contain ~18% Al or more.. Good oxide and sulfur resistance, with strength comparable to steel alloys, and low cost of materials have made these compounds of metallurgical interest - however low ductility and issues with hydrogen embrittlement are barriers to their processing and use in structural applications.
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.
“The existing evidence suggests that this compound can cause liver, developmental, blood and endocrine effects in the human body,” Jamie Alan, an associate professor of pharmacology and ...
Metal toxicity or metal poisoning is the toxic effect of certain metals in certain forms and doses on life.Some metals are toxic when they form poisonous soluble compounds. . Certain metals have no biological role, i.e. are not essential minerals, or are toxic when in a certain for

Reports have emerged of animals dying of bird flu in various parts of the U.S. (not pictured). The USDA recently issued a new order that all raw (unpasteurized) milk must be tested for the virus.
