What are the advantages and disadvantages of zirconia ceramics
Zirconia ceramic is a kind of high temperature, high strength, high hardness, corrosion resistance and excellent insulation properties of the material, is widely used in aviation, aerospace, chemical, electronic, medical and other fields. However, zirconia ceramics also have some disadvantages. The advantages and disadvantages of zirconia ceramics are discussed in this paper.
I. Advantages
1. High strength: Zirconia ceramics have high strength and hardness, especially bending strength and tensile strength, which is several times or even dozens of times that of steel.
2. High temperature performance: Zirconia ceramics still maintain high strength and hardness at high temperatures, and can withstand high temperature corrosion and thermal shock.
3. High insulation: Zirconia ceramics have high electrical and thermal insulation, and can be used to manufacture high-voltage insulators, electronic components and so on.
4. Corrosion resistance: Zirconia ceramics have good corrosion resistance and can be used to manufacture chemical equipment and Marine engineering equipment.
What are the advantages and disadvantages of zirconia ceramics
5. Light weight: Zirconia ceramics are less dense and lighter than steel, which can reduce the weight of objects.
Ii. Disadvantages
1. Brittleness: Zirconia ceramics have high hardness and strength, but they are also brittle and easy to break or crumble.
2. High price: zirconia ceramics have higher production costs and more expensive prices, which limits its application in some fields.
3. Poor water resistance: zirconia ceramics are easily damaged in water for a long time, and are not suitable for making underwater equipment.
4. Poor thermal stability: The thermal stability of zirconia ceramics is poor, and it is easy to phase change at high temperatures, resulting in a decline in performance.
Zirconia ceramics have the advantages of high strength, high temperature performance, high insulation, corrosion resistance and light weight, but it also has some disadvantages such as brittleness, high price, poor water resistance and poor thermal stability. Usually, ceramic parts are processed using special ceramic engraving machining, which can effectively reduce costs and achieve high precision machining.
