Pure silicon is too reactive to be found in nature, but it is found in practically allrocksas well as insand,clays, andsoils, combined either with oxygen as silica (SiO2, silicon dioxide) or with oxygen and other elements (e.g.,aluminum,magnesium,calcium,sodium, potassium, or iron) assi...

FeCl3. The TiCl4is then reduced with moltenmagnesiumat about 800 °C (1,500 °F) in an atmosphere ofargon, and metallic titanium is produced as a spongy mass from which the excess of magnesium and magnesium chloride can be removed by volatilization at about 1,000 °C (1,800 °F). Th...
Al: high-potential aluminum is a harmful element, it can form a cathode phase with magnesium to speed up the corrosion rate, the presence of aluminum also reduces the solubility of manganese in magnesium. The role of the main elements in the low potential anode: ...
It has a high acid-binding capacity and reacts rapidly to neutralize gastric acid. The ingestion of pure magnesium hydroxide antacids leads to undesirably high pH values in the stomach, which can, in turn, stimulate acid production. 因此,建议在抗酸制剂中将氢氧化镁与氢氧化铝结合使用。Combination...
