Ceramic Materials
Ceramic materials are natural or synthetic compounds after forming and sintering temperature of a class of
inorganic non-metallic materials. It has the advantage of high melting point , high hardness , high wear
resistance , resistance to oxidation and the like. Used as a structural material , tool material, since the
ceramic also has some special properties , but also as functional materials.
Mechanical properties
Ceramic materials are engineering materials stiffness Preferably , the highest hardness of the material , mostly
in hardness 1500HV or more. Ceramic high compressive strength but low tensile strength , ductility and toughness
is poor.
Thermal Characteristics
Ceramic materials generally have a high melting point ( mostly above 2000 ℃), and has excellent chemical
stability at high temperatures ; ceramic thermal conductivity is lower than a metallic material , a ceramic or a
good heat insulating material . While the linear expansion coefficient of the ceramic is lower than that of
metal , when the temperature changes , the ceramic has good dimensional stability.
Electrical characteristics
Most ceramics have good electrical insulation properties , and therefore produce a large number of various
voltages (1kV ~ 110kV) of the isolation device is used . Ferroelectric ceramics ( barium titanate BaTiO3) having
a high dielectric constant , can be used for the production of capacitors , under the action of an external
electric field of ferroelectric ceramics , can change shape , converting electrical energy into mechanical
energy ( having the characteristics of the piezoelectric material ) , can be used as amplifiers, record players
, ultrasonic instrument, sonar , and other medical sonographer . Ceramic also has a few properties of
semiconductors can be used as a rectifier.
Chemical properties
Ceramic materials easily oxidized at high temperatures , and acid , alkali, salt has good corrosion resistance.
Optical properties
Ceramic materials as well as the unique optical properties, can be used as solid-state laser materials, fiber
materials, optical storage devices , etc., can be used for high-pressure sodium lamp transparent ceramic tubes.
Magnetic ceramic ( ferrite such as : MgFe2O4, CuFe2O4, Fe3O4) in the audio tape , the application records,
transformer core , large computer memory device has a wide range of aspects of the future
Following is our company detail:Our factory has specilized in die cast car manufacturers buy aluminium die
casting，die cast aluminium，aluminum enclosur for many year since 2002. And our products are always well
received and approved by our customers from Asian, European, North American and Australian etc.
