Application of magnesium-stabilized zirconia ceramics
Magnesium-stabilized zirconia ceramics are widely used in several fields due to their unique performance characteristics:
1. Industrial applications:
Wear-resistant parts: Used in the manufacture of highly wear-resistant mechanical parts, such as pump bushings, sealing rings and valve components, which can significantly extend the service life of the equipment.
Cutting tools: Used in the manufacture of cutting tools and cutting tools, due to its high hardness and wear resistance can maintain good performance in high-precision machining.
2. Aerospace:
High-temperature components: Used as high-temperature structural components in aero-engines and gas turbines, capable of withstanding extremely high temperatures and pressurized environments.
Thermal Barrier Coatings: Surface coatings for turbine blades and other high-temperature components that provide excellent thermal protection.
3. Electronic and electrical:
Insulators and substrates: Used as insulators and substrates for high-frequency circuits and power electronics due to their excellent electrical insulation properties and thermal stability.
4. Chemicals and energy:
Catalyst Carrier: Used in the chemical industry as a catalyst carrier, providing good chemical stability and high temperature performance.
Fuel Cell Components: Used as an electrolyte material in solid oxide fuel cells, its ionic conductivity and high temperature resistance enhance cell efficiency and life.
Magnesium-stabilized zirconia ceramics play a key role in a variety of fields thanks to their excellent physical and chemical properties, significantly enhancing the performance and durability of equipment.
Basic properties of magnesium-stabilized zirconia ceramics
Magnesium-stabilized zirconia ceramics use magnesium oxide (MgO) as a stabilizer for zirconia, and the crystal structure is cubic lattice after molding, which is more stable. Magnesia-zirconia has better resistance to high temperature and humidity because it is not affected by phase migration. Magnesia-zirconia maintains its strength even in humid, high-temperature environments where the mechanical properties of yttrium oxide partially stabilized zirconia begin to deteriorate.
