Zirconia Toughened Alumina (ZTA) ceramics offer superior performance compared to other materials and can be used in a variety of industrial environments with key performance characteristics including:

• High Strength:ZTA ceramics have the high hardness of aluminum oxide and can withstand enormous mechanical loads.

• Fracture toughness:ZTA ceramics have the good toughness of zirconium oxide, where tiny zirconium oxide particles transform into stress-absorbing microcracks on impact, preventing catastrophic failure and increasing fracture toughness by several times compared to pure aluminum oxide.

• Thermal Stability:ZTA ceramics are unaffected by searing temperatures and rapid thermal fluctuations and are able to stand up to harsh environments.

• Chemical resistance:ZTA ceramic substrates are highly resistant to corrosion and aggressive chemicals, ensuring long-lasting performance.

Zirconia Toughened Alumina (ZTA) ceramics are widely used in the following industries due to their excellent comprehensive performance:

• Pump and valve industry:Ideal for wear parts on pumps, valves and agitators handling abrasive fluids and slurries.

• Food and beverage processing:Contamination-free washers for food processing equipment ensure hygiene and purity.

• Chemical and pharmaceutical industries:Resistant to harsh chemicals and corrosive environments in reactors, stirrers and other equipment.

• Textile industry:Provides smooth, wear-resistant washers for guide rollers and tensioning devices to improve yarn and fabric quality.

• Aerospace and Defense:Light weight and high strength make them suitable for demanding aerospace and defense applications.

From unremarkable powders to polished substrates, the process of preparing zirconia-toughened alumina (ZTA) ceramics involves the following steps:

• Preparation of ceramic powders:The ceramic powder was prepared by using ball mill, ball mill and spray dryer to control the dosage.

• Pressing of raw materials:The raw material is pressed into the desired shape and density.

• Sintering process:ZTA ceramics are sintered by hot pressing, hot isostatic pressing, and continuous hot press sintering.

ZTA ceramics are increasingly used in a variety of industrial production environments due to their versatility and superior performance compared to other materials. The popularity of ZTA ceramics in the industry is expected to increase as the demand for high-quality ceramic parts continues to grow.
