Zirconia Toughened Alumina Powder Description
Zirconia toughened alumina powder is a white ceramic powder featuring low sintering temperature and uniform dispersion of both phases. After firing, the green body is easy to machine and offers a smooth surface finish. The final ceramic products are lightweight, strong, tough, and highly resistant to wear, corrosion, and high temperatures. This powder is widely used as a raw material for structural ceramic parts, including cutting tool bases, molds, wear-resistant bushings, valve seats, pump components, and textile machinery parts.

Zirconia Toughened Alumina Material Properties
Zirconia Toughened Alumina Material Grades
CeramAlloy ZTA is a high performance ceramic composite and a unique ceramic material by way of exhibiting a combination of high hardness, strength, wear and corrosion resistance resulting from its Alumina content, while still maintaining reasonably high fracture toughness resulting from its Zirconia content.
Applications:
- High pressure equipment – ball valve balls and seats
- Rollers and guides for metal forming
- Thread and wire guides
- Deep well down-hole valves and seats
- Shaft bearings/bushings
Ultra Hard is a high performance ceramic composite and a unique ceramic material by way of exhibiting a combination of high hardness, strength, wear and corrosion resistance resulting from its Alumina content, while still maintaining reasonably high fracture toughness resulting from its Zirconia content.
Applications:
- High pressure equipment – ball valve balls and seats – particularly suitable for high flow/abrasive fluids
- Focusing nozzles for abrasive media
- Ultra high pressure pumping elements
- Deep well down-hole valves and seats
- Rollers and guides for metal forming
- Thread and wire guides
- Metal extrusion dies
Zirconia Toughened Alumina Powder Packaging
The zirconia toughened alumina powder is typically packaged in sealed, moisture-proof plastic bags, then placed in sturdy drum containers or fiber cartons to prevent contamination and ensure safe transport. Standard packaging sizes include 1 kg, 5 kg, and 10 kg options, with custom packaging available upon request to meet specific usage or storage needs.
