High toughness zirconia toughened ceramic plate

High toughness zirconia toughened ceramic plate, also known as ZTA ceramic, is an advanced ceramic material that combines the high toughness of zirconia with the excellent hardness of alumina.

This material has the following characteristics:
High strength and toughness: ZTA ceramics significantly improve the impact resistance of materials through toughening technology, with extremely high crack resistance, suitable for use in harsh environments, and can effectively reduce the risk of material fracture.
High temperature resistance: It can maintain stability in high temperature environments and is suitable for metallurgy, chemical engineering, and high-temperature processes. The working temperature can reach up to 1500 ° C.
Excellent wear resistance: The high hardness and good wear resistance of ZTA ceramics make them excellent in wear environments and widely used in abrasive, cutting tool and other fields, extending the service life of equipment.
Good chemical stability: It has strong resistance to most chemical media and corrosive environments, and can work stably for a long time in harsh environments, reducing equipment failures and maintenance costs.
Excellent electrical insulation: ZTA ceramics have excellent electrical insulation properties and can be used in high-frequency and high-voltage environments to ensure the safety of electronic and electrical equipment.
Thermal stability: With a low coefficient of thermal expansion, it can maintain dimensional stability in high-temperature and thermal cycling applications, effectively preventing stress problems caused by temperature differences.

In terms of application, ZTA ceramic copper-clad substrates are widely used in electric vehicle IGBT, LED and other fields. The low fracture toughness and poor impact resistance of alumina limit its wider application in various fields. By adding toughening materials such as zirconia to the alumina matrix, this phenomenon can be significantly improved, thereby expanding the application range of alumina ceramics.
