magnesium | Description, Properties, & Compounds

Magnesium hydroxide, Mg(OH) 2, is a white powder produced in large quantities from seawater by the addition of milk of lime (calcium hydroxide).It is the primary raw material in the production of magnesium metal and has been used as a fire-retardant additive. In water it forms a suspension known as milk of magnesia, which has long been used as an antacid and a laxative.

Sodium hydroxide | NaOH - PubChem

Sodium hydroxide has depilatory effects which have been described after accidental contact with solutions in the workplace. The breakage of bonds in proteins may lead to severe necrosis to the appliion site. The level of corrosion depends on the period of contact with the tissue, and on the concentration of sodium hydroxide [L1975].

By controlling the morphological dimensionality, low dimensional metal halide perovskites, including 2D perovskite nanoplatelets, 1D perovskite nanowires, and 0D perovskite quantum dots, have been developed to exhibit distinct properties from their bulk counterparts, due to quantum size effects.

Metal Profile: Iron Properties and Characteristics

Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores. The carbon within the wood would have reacted with the oxygen in the ore, leaving a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BC.
