ZTA based ceramics
ZTA based ceramics
ZTA is a combination of alumina and 10-20% zirconium
ZTA Properties:- Extra strength and toughness compared to alumina;
- Lower cost than zirconia;
- High corrosion resistance;
- High fracture toughness;
- High bending strength.
Areas of use:
- Insulators, sensors, piston bushings and pump components;
- Fluid supply system components;
- LED Chip Carriers.
LLC NPO GKMP supplies custom-made ceramic products based on ZTA according to customer drawings.
