Custom Step Perforated Alumina Ceramic Sheet

Mechanical properties
Ceramic material is the material with the best stiffness and hardness among engineering materials, and its hardness is mostly above 1500hv. Ceramics have high compressive strength, but low tensile strength, poor plasticity and toughness.
Thermal characteristics
Ceramic materials generally have a high melting point (mostly above 2000 ℃) and excellent chemical stability at high temperature; the thermal conductivity of ceramic is lower than that of metal materials, and ceramic is also a good thermal insulation material. At the same time, the linear expansion coefficient of ceramic is lower than that of metal. When the temperature changes, ceramic has good dimensional stability.
Electrical characteristics
Most ceramics have good electrical insulation, Therefore, it is widely used to make insulating devices with various voltages (1kV ~ 110kV). Ferroelectric ceramics (barium titanate BaTiO3) have high dielectric constant and can be used to make capacitors. Under the action of external electric field, ferroelectric ceramics can also change shape and convert electrical energy into mechanical energy (with the characteristics of piezoelectric materials), it can be used as loudspeaker, phonograph, ultrasonic instrument, sonar, medical spectrometer, etc. a few ceramics also have the characteristics of semiconductors and can be used as rectifiers.
chemical properties
Ceramic materials are not easy to oxidize at high temperature, and have good corrosion resistance to acid, alkali and salt.
optical characteristics
Ceramic materials also have unique optical properties. They can be used as solid-state laser materials, optical fiber materials, optical storage, etc. transparent ceramics can be used in high-pressure sodium lamps, etc. Magnetic ceramics (such as MgFe2O4, cufe2o4 and Fe3O4) have a wide range of applications in recording tapes, records, transformer cores and memory components of large computers.
