Zibo ceramic meals are an indispensable part of our daily life. Most people's tableware generally choose ceramic products. So, what properties do ceramic meals have?
It 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.
2. Thermal characteristics
Generally has a high melting point (mostly above 2000 ° C), and has 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.
3. Electrical characteristics
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.
4. Chemical properties
It is not easy to oxidize at high temperature, and has good corrosion resistance to acids, alkalis and salts.
5. Optical characteristics
It also has 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 the explanation of each performance of Zibo ceramic tableware. If you are interested in Zhiyuanyuan Ceramics, you are welcome to consult us.
