说明

据报道，氧化镁（MgO）是一种工业上重要的高温材料。 锂掺杂的氧化镁 (Li/MgO) 可用于从甲烷合成乙烯和乙烷。 它作为二氧化碳环加成环氧化物的催化剂参与。 它在二氧化碳与 (R)-苯乙烯反应生成 (R)-碳酸苯酯的过程中起催化剂的作用。
氧化镁可用作宽带隙绝缘体。 它可以进行水合得到氢氧化镁纳米颗粒。
在多孔 β-磷酸三钙 (β-TCP) 的制造过程中，氧化镁 (MgO) 可用作相稳定剂。

一般描述

Magnesium oxide (MgO) has been reported as an industrially important high-temperature material. Lithium-doped magnesium oxide (Li/MgO) may be employed for the synthesis of ethylene and ethane from methane. It participates as a catalyst for the cycloaddition of carbon dioxide to epoxide. It plays the role of a catalyst during the reaction of carbon dioxide with (R)-styrene to afford (R)-phenyl carbonate.
Magnesium oxide can be used as a wide-band-gap insulator. It can undergo hydration to give magnesium hydroxide nanoparticles.
 

应用

Magnesium oxide (MgO) may be employed as a phase stabilizer during the fabrication of porous β-tricalcium phosphate (β-TCP).
