Vietnamese Céramique spinelle d'aluminate de magnésium (MgAl₂O₄)
What is the Magnesium Aluminate Spinel Ceramic (MgAl₂O₄) ?
Magnesium aluminate spinel ceramic, with the chemical formula MgAl₂O₄, is an advanced ceramic material widely used for crucibles or as liners in the melting industry. Its main component is MgAl₂O₄. Its dense and vitrified structure provides higher thermal shock resistance. Magnesium aluminate spinel can be further categorized into magnesia-rich spinel and alumina-rich spinel, based on the varying content of the two key components—magnesia and alumina—in the synthesized spinel.

Application of Magnesium Aluminate Spinel Ceramic
Magnesium aluminate spinel, with its low thermal expansion coefficient after sintering, is commonly used to manufacture crucibles and liners for the melting industry. For instance, magnesium aluminate spinel crucibles are highly resistant to corrosion from molten neodymium-iron-boron steel and can be used for melting permanent magnets or rare earth materials. Additionally, there remains significant untapped potential for the application of magnesium aluminate spinel ceramics in alloy melting processes.
