(1) Mechanical aspects. ZTA zirconium aluminum composite ceramics have the characteristics of high hardness, strong mechanical properties at high temperature, good wear resistance, good chemical stability, and are not easy to bond with metals, and are widely used in the cutting of some difficult-to-process materials such as hard material cutting, high-speed steel cutting, and ultra-high-speed cutting.

(2) Industry. At present, there are many types of industrial valves, and alumina industrial valves are commonly used plug valves, gate valves, globe valves, ball valves, etc.

(3) Electronics, electricity. There are various alumina ceramic base plates, substrates, ceramic films, transparent ceramics and various alumina ceramic electrical insulating porcelains, electronic materials, magnetic materials, etc., among which alumina transparent ceramics and substrates are the most widely used.

(4) Chemical industry. In terms of chemical applications, alumina ceramics also have a wide range of uses, such as alumina ceramic chemical packing balls, inorganic microfiltration membranes, corrosion-resistant coatings, etc., among which alumina ceramic membranes and coatings are the most studied and applied.
