There are several types of zirconia ceramics, the most common being yttrium oxide partially stabilized zirconia (Y-PSZ) and magnesium oxide partially stabilized zirconia (Mg-PSZ). Their unique resistance to crack propagation and high thermal expansion make them excellent for joining ceramics to metals such as steel. Due to its high wear and corrosion resistance, Mg-PSZ is used in valves, pumps and gaskets. Magnesium-stabilized zirconia is also the material of choice for the chemical processing and petrochemical industries. Therefore, zirconia ceramic products are ideal for many industries such as:

• Precision shafts in high wear environments;
• Refractory materials;
• Bushings and covers;
• Fiber optic ferrule and sleeve;
• Cutters and blades;
• Fuel cell parts;
• Bearings and rollers;
• Electrical insulators;
• Oxygen Sensor;
• Medical and surgical components;
• Mechanical seal assembly;
• Pumps, pistons and cylinder liners.

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.
