O QUE SIGNIFICA MAGNESIUM OXIDE EM INGLÊS
Óxido de magnésio
Óxido de magnésio (MgO), ou magnésia, é um mineral sólido higroscópico branco que ocorre naturalmente como periclase e é uma fonte de magnésio (veja também o óxido). Possui uma fórmula empírica de MgO e consiste em uma rede de íons Mg2 + e íons O2- unidos por ligação iônica. O hidróxido de magnésio se forma na presença de água (MgO + H2O → Mg (OH) 2), mas pode ser revertido aquecendo-o para separar a umidade. O óxido de magnésio era historicamente conhecido como magnesia alba (literalmente, o mineral branco de Magnesia - outras fontes dão magnesia alba como MgCO3), para diferenciá-lo da magnésia negra, um mineral preto contendo o que agora é conhecido como manganês. Enquanto normalmente "óxido de magnésio" significa composto MgO, o peróxido de magnésio MgO2 é também conhecido como um composto metaestável. De acordo com a previsão evolutiva da estrutura cristalina, o MgO2 é termodinamicamente estável a pressões acima de 116 GPa, e um subóxido semicondutor Mg3O2 totalmente novo é termodinamicamente estável acima de 500 GPa.
definição de magnesium oxide no dicionário inglês
A definição de óxido de magnésio no dicionário é uma substância insípida branca que ocorre naturalmente como periclase: usada como antiácido e laxante e em materiais refratários, como cadinhos e tijolos de fogo. Fórmula: MgO Também chamado de magnésia.

The Complete Guide to High-Fire Glazes
Magnesium oxide is an alkaline earth flux and has one of the highest melting
points of all the ceramic oxides, 5072°F (2800°C), but it begins its fluxing action
around 2138°F (1170°C), forming eutectics with other oxides so that it can melt at

Diffusion of oxygen in
magnesium oxide
This is consistent with an oxygen vacancy mechanism. Under conditions appropriate for intrinsic diffusion, magnesium oxide is shown to be an oxygen excess structure. Charge compensation is by formation of trapped-hole defects.
