Magnesium Oxide Metal Or Ceramic

Magnesia is the common name used for magnesium oxide mgo.

Magnesium oxide metal or ceramic.

Classify each of the following materials as to whether it is a metal ceramic or polymer. Magnesium oxide performs excellently in high temperatures particularly in the creation of electrical insulation where our luminex range excels. Magnesium oxide mg o or magnesia is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium see also oxide it has an empirical formula of mg o and consists of a lattice of mg 2 ions and o 2 ions held together by ionic bonding. Magnesium oxide is extracted from seawater magnesite deposits and or brines and subsequently processed through heat treatment and grinding.

Magnesia has a maximum use temperature of 2200ºc which is significantly higher than many other technical ceramics. Magnesium hydroxide forms in the presence of water mgo h 2 o mg oh 2 but it can be reversed by heating it. Preparation of the high toughness ceramic materials using high purity magnesium oxide and yttrium oxide or rare earth metal oxides as composite stabilizers to produce partially stabilized zirconia ceramics with excellent mechanical properties and high temperature ageing resistance. The typical process for crushable tubes made of magnesium oxide is extrusion.

Whilst dense magnesia has limited uses as an engineering ceramic lower density variants of magnesia such as our luminex material can be utilised in a range of market sectors and industry specific applications. Mgo belongs to the c820 material group and is used in various purities with mgo contents between 90 and 99. The material has an extremely useful combination of properties which distinguish it from other ceramics.
