ZTA ceramic insulator

ZTA ceramic insulator is a high-performance ceramic insulation material composed of a composite of aluminum oxide (Al ₂ O3) and zirconium oxide (ZrO ₂). This material combines the high insulation and high temperature resistance of alumina with the toughening properties of zirconia, resulting in excellent mechanical strength, impact resistance, and thermal shock resistance, making it suitable for harsh industrial environments.
Product Features
-High mechanical strength: ZTA ceramics have better bending strength and fracture toughness than ordinary alumina ceramics, and can withstand higher mechanical stresses.
-Excellent insulation performance: high resistivity and low dielectric loss, suitable for high-voltage and high-frequency electrical environments.
-High temperature resistance: It can work stably for a long time in high temperature environments above 1000 ° C.
-Thermal shock resistance: Due to the phase transformation toughening effect of zirconia, ZTA ceramics can withstand rapid temperature changes without cracking.
-Corrosion resistance: It has excellent corrosion resistance to acids, alkalis, and organic solvents.

The problems that the product can solve
The design of ZTA ceramic insulators aims to solve the problem of insufficient performance of traditional insulation materials in extreme environments, including:
-Insufficient mechanical strength: Ordinary ceramics are fragile, while ZTA ceramics have stronger impact resistance, reducing the risk of fracture.
-Poor thermal stability: In high temperature or rapidly changing temperature environments, ordinary insulation materials are prone to cracking. The thermal shock resistance of ZTA ceramics can effectively avoid this problem.
-Insulation failure: Under high voltage or high frequency conditions, traditional materials may experience breakdown, and the high insulation properties of ZTA ceramics ensure long-term stability.
-Insufficient corrosion resistance: In industries such as chemical and metallurgical, ZTA ceramics can resist the erosion of corrosive media and extend their service life.

ZTA ceramic insulators have become an ideal choice for industries such as power, electronics, and new energy due to their advantages of high strength, high insulation, high temperature resistance, and thermal shock resistance.
