DESCRIPTION
General description
Magnesium oxide (MgO) has been reported as an industrially important high-temperature material.[1] Lithium-doped magnesium oxide (Li/MgO) may be employed for the synthesis of ethylene and ethane from methane.[2] 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.[3] Magnesium oxide can be used as a wide-band-gap insulator.[4] It can undergo hydration to give magnesium hydroxide nanoparticles.[5]
Application
Magnesium oxide (MgO) may be employed as a phase stabilizer during the fabrication of porous β-tricalcium phosphate (β-TCP).[6]
