Magnesium in biology be used as adjuvant therapy in patients on optimal treatment for severe congestive heart failure, increasing survival rate and improving clinical symptoms and patient's quality of life. Magnesium can affect muscle relaxation through direct action on cell membranes. Mg ions close certain types of calcium channels, which conduct positively charged calcium ions into neurons. With an excess of magnesium, more channels will be blocked and nerve cells activity will decrease. Intravenous magnesium sulphate is used in treating pre-eclampsia. For other than pregnancy-related hypertension, a meta-analysis of 22 clinical trials with dose ranges of 120 to 973 mg/day and a mean
Magnesium silicide in the interior of the unit cell. The coordination numbers of Si and Mg are eight and four, respectively. Magnesium silicide Magnesium silicide, MgSi, is an inorganic compound consisting of magnesium and silicon. It can be produced by heating silicon dioxide, SiO, found in sand, with excess magnesium. The process first forms silicon metal and magnesium oxide, and, if an excess of magnesium is used, the silicide is formed: If an excess of Mg is present, MgSi is formed from the reaction of the remaining magnesium with the silicon: These reactions proceed exothermically. Magnesium silicide is used to create aluminium
