Qi Zhiyuan ceramics are common items in our daily life. Our commonly used bowls and cups have ceramics. So, do you know what the properties of Qi Zhiyuan ceramics are? Xiaobian will tell you about What are the properties of ceramics?
Qi Zhiyuan ceramic material is the material with the best rigidity and the highest hardness among engineering materials, and its hardness is mostly above 1500HV. Ceramics have higher compressive strength, but lower tensile strength, and poor plasticity and toughness.
Qi Zhiyuan ceramic materials generally have a high melting point (mostly above 2000 ° C), and have excellent chemical stability at high temperatures; the thermal conductivity of ceramics is lower than that of metal materials, and ceramics are also good thermal insulation materials. At the same time, the linear expansion coefficient of ceramics is lower than that of metals. When temperature changes, ceramics have good dimensional stability.
Most ceramics have good electrical insulation, so they are widely used to make insulation devices of various voltages (1kV ~ 110kV). Ferroelectric ceramics (barium titanate BaTiO3) have high dielectric constants and can be used to make capacitors. Ferroelectric ceramics can also change shape and convert electrical energy into mechanical energy (with the characteristics of piezoelectric materials) under the action of an external electric field. It can be used as loudspeaker, record player, ultrasonic instrument, sonar, medical spectrometer, etc. A few ceramics also have semiconductor characteristics and can be used as rectifiers.
Qi Zhiyuan ceramic material is not easy to oxidize at high temperature, and has good corrosion resistance to acids, alkalis and salts.
Qi Zhiyuan ceramic materials also have unique optical properties, which can be used as solid laser materials, optical fiber materials, optical storage, etc. Transparent ceramics can be used for high-pressure sodium lamps. Magnetic ceramics (such as ferrites: MgFe2O4, CuFe2O4, Fe3O4) have a wide range of applications in audio tapes, records, transformer cores, and large-scale computer memory components.
The above is an introduction to the performance of Qizhiyuan Ceramics . Do you know about it? If you are interested or have any questions about Ziyuanyuan Ceramics, please feel free to contact us.
