Magnesium diboride is the inorganic compound with the formula MgB 2. It is a dark gray, water-insoluble solid. The compound has attracted attention because it becomes superconducting at 39 K (−234 °C). In terms of its composition, MgB 2 differs strikingly from most low-temperature superconductors, which feature mainly transition metals.
Magnesium glycinate, also known as magnesium diglycinate or magnesium bisglycinate, is the magnesium salt of glycine (one magnesium and two glycine molecules), and is sold as a dietary supplement. [ 1][ 2] It contains 14.1% elemental magnesium by mass. Magnesium glycinate is also often "buffered" with magnesium oxide but it is also available in ...
Flash powder is a pyrotechnic composition, a mixture of oxidizer and metallic fuel, which burns quickly (deflagrates) and produces a loud noise regardless of confinement. It is widely used in theatrical pyrotechnics and fireworks (namely salutes, e.g., cherry bombs, M-80s, firecrackers, and cap gun shots) and was once used for flashes in ...
Magnesium aspartate is a compound formed by the combination of the divalent magnesium cation (Mg2+) and the dicarboxylic amino acid aspartate (C4H6NO4-). [ 1] The chemical formula for this compound is Mg (C4H6NO4)2. [ 7] The structure of magnesium aspartate consists of a central magnesium ion that is chelated, or bound, by two aspartate anions.
Magnesium oxide ( Mg O ), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide ). It has an empirical formula of MgO and consists of a lattice of Mg 2+ ions and O 2− ions held together by ionic bonding. Magnesium hydroxide forms in the presence of water (MgO + H 2 O ...
Magnesium stearate is the chemical compound with the formula Mg (C. 18H. 35O. 2) 2. It is a soap, consisting of salt containing two equivalents of stearate (the anion of stearic acid) and one magnesium cation (Mg 2+ ). Magnesium stearate is a white, water-insoluble powder. Its applications exploit its softness, insolubility in many solvents ...
Magnesium sulfate as a medication is used to treat and prevent low blood magnesium and seizures in women with eclampsia. [ 1] It is also used in the treatment of torsades de pointes, severe asthma exacerbations, constipation, and barium poisoning. [ 1][ 2] It is given by injection into a vein or muscle as well as by mouth. [ 1][ 2] As epsom ...
The U.S. Food Chemicals Codex, [6] JECFA, [7] and other monographs for Food Grade synthetic magnesium silicate specify a mole ratio of 2MgO:5SiO 2 (or X=2.5 in the general formula). The most common use for Food Grade synthetic magnesium silicate is as an active filter aid for adsorption of color, free fatty acids and other polar compounds from ...
