Advantages of Black Zirconia Ceramic Cavity Structures

The biggest advantage of zirconia is its high strength and toughness, which is superior to ordinary ceramics, and it can still maintain dimensional stability and is not easy to be deformed under high temperature environment.

High strength and toughness for a more durable structure
Extremely high abrasion resistance
High temperature resistance and good thermal stability
Excellent corrosion resistance
Premium appearance, suitable for high-end equipment

Application of magnesium-stabilized zirconia ceramics

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.

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.
