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.
