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.
