Description: Zirconia Toughened Alumina (ZTA) Ceramic Disc
Zirconia toughened alumina ceramics (ZTA), features white quality, corrosion resistance, good chemical stability. Alumina has high hardness, while zirconia has good toughness, the two materials combined form a high strength, high toughness material, which is widely used in machinery, electronics, petroleum, chemical, aerospace and textile industries. The specific ratio of the two materials can be adjusted according to the actual requirements of users.
