Introduction
Magnesium oxide (MgO) and zirconia (ZrO₂) are relevant inorganic compounds known for their distinctive properties and complementary characteristics. Magnesium oxide is a highly thermostable white powder with electric insulation. It is used widely in refractories, ceramics, and as a dietary supplement. At the same time, zirconia is valued for its high hardness, chemical resistance, and biocompatibility. Magnesium Oxide & Zirconia (MgO & ZrO₂) form a composite material widely used in thermal spray applications due to its exceptional thermal stability, wear resistance, and thermal shock resistance.
