Description

Zirconia Toughened Alumina Ceramics (referred to as composite ceramics, ZTA) has the characteristics of corrosion resistance and chemical stability. Alumina has high hardness and the toughness of zirconia is good. The composite ceramics have the properties of both materials, it has higher flexural strength and fracture toughness at room temperature, and zirconia toughened ceramics have excellent wear resistance, high strength, and hardness.

The performance of ZTA ceramics is better than that of 99 alumina ceramics, and the price is much lower than that of zirconia ceramics. The specific ratio of the two materials can be adjusted according to the application. Typically, ZTA contains 10-20% volume of ZrO2 in alumina. Depending on the percentage of content, the properties of the ceramic can be tailored to suit the application in question.

Packing of Zirconia Toughened Alumina Products

Our ZTA products are clearly tagged and labeled externally to ensure efficient identification and quality control. The products are separated by bubble bags for shockproof purposes and finally packed in wooden or carton boxes. Great care is taken to avoid any damage which might be caused during storage or transportation.
