ZTA ceramic is a zirconia-toughened alumina ceramic, which is an inorganic non-metallic material with excellent properties such as high hardness, high strength, and high toughness. ZTA ceramics add zirconia to alumina ceramics. Through phase change toughening and micro-crack toughening, the alumina ceramics are toughened and reinforced, thereby improving the toughness of the alumina ceramics.

 Zirconia Toughened Alumina (ZTA) introduces ZrO₂, Cr₂O₃ and TiO₂ with similar lattices to Al₂O₃ in the ceramic formula, resulting in higher strength and toughness than alumina ceramics. 

Advantages of ZTA ceramics:

High hardness: ZTA ceramic has a very high hardness, second only to diamond, has excellent wear resistance and durability, and can withstand a large amount of friction and wear.
High strength: ZTA ceramic has excellent flexural strength and compressive strength, can remain stable under high temperature and pressure, and is not easy to deform or break.
High toughness: ZTA ceramics have good toughness and can be used under high-speed, high-pressure, and high-impact conditions and are not easily broken.
Good corrosion resistance: ZTA ceramics have good corrosion resistance to chemicals such as acids, alkalis, and salts, and are not easily corroded or chemically reacted.
Good thermal stability: ZTA ceramics can be used at high temperatures, are not prone to thermal expansion and contraction, and have very good thermal stability.

Application scenarios of ZTA ceramics:

Medical device field: ZTA ceramics are biocompatible and corrosion-resistant and can be used to manufacture rigid components of artificial joints, providing good bone bonding and durability.
Electronic device field: ZTA ceramics have good thermal and electrical insulation properties and can be used to manufacture insulating materials for high-temperature electronic devices.
Wear-resistant lining field: ZTA ceramic tiles are used as wear-resistant linings for heavy wear parts in mines, docks, and factories, and have a long service life.
Other areas: ZTA ceramics can also be used in pumps, valve seals, bushings, pump parts, cutting tools and engine components.
