Advanced Mg-Psz MGO Partially Stabilized Zirconia Ceramic Magnesia-stabilized parts

With the advancement of technology, ceramic materials can be made with a variety of ingredients and a number of processing techniques for industrial and engineering use. These ceramics are known as advanced ceramics or industrial ceramics. Zirconia ceramics are the ideal choice for electrical and mechanical components use due to their special high performance properties

Zirconia has excellent strength and high resistance to corrosion, wear and abrasion. Since it has a high tolerance to degradation, zirconia is the suitable choice in the manufacturing of bearings, bushings, seals and grinding. Further thanks to its high resistance to developing cracks, commonly referred to as 'fracture toughness', zirconia is widely used in structured ceramics, oxygen sensors and dental ceramics.

Conventional zirconias contain the metastable transformable particles, so stabilizing need to performed to prevent phase transformation. MgO partial stabilized zirconia (Mg-PSZ) was achieved by adding less MgO stabilizer than necessary to provide a consistent cubic structure, the rest remains transforming between monoclinic below and tetragonal above the transformation temperature. So it got a drastically reinforced strength and resistance to temperature changing.
