Zirconia Ceramic Shaped Structural Partsmerits
The greatest advantage of zirconia ceramic shaped structural parts is that they can simultaneously meet the needs of complex shape design and high-performance material requirements. Although ordinary metal parts are easy to process, there are problems of insufficient wear resistance, rust, electrical conductivity and high-temperature dimensional drift; although ordinary ceramics have high hardness, they are prone to chipping at complex thin edges and holes and grooves. Zirconia ceramics through the advantages of high toughness and high strength, successfully balance the safety of complex structures and long-term stability. Especially in high-precision, high-clean and high-reliability equipment, the advantages are more obvious.
Description
Advantages of zirconia ceramic shaped structural parts
Zirconia ceramics, as a high-performance material representative of advanced engineering ceramics, has multiple advantages such as high toughness, high strength, super wear resistance, corrosion resistance and high dimensional stability, which is very suitable for long-term and stable application of complex non-standard and shaped structural parts, and it is an important upgraded material for replacing metal and common ceramics in high-end industrial fields.
- High toughness and strong crack resistance, complex shaped structure is safer.
- Superior abrasion resistance to maintain critical structural dimensions over time
- Outstanding heat-resistant and heat-insulating properties
- Excellent electrical insulation properties

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.
