Ceramic injection molding for electronic products

Ceramic material mainly composed of zirconia and alumina, zirconia can effectively make waves through.,which is electronic products ideal material.

Ceramic material is made from natural or synthetic compounds by forming and high temperature sintering of inorganic non-metallic materials.It has advantages of high melting point, high hardness, high wear resistance, and oxidation resistance. Can be used as a structural material, cutting tool material, because the ceramic also has some special properties, and can be used as functional materials. Even some of the best ceramic material is applied to the high-end watches.

Ceramics material properties

Ceramic material is the best of the engineering material in stiffness and hardness, hardness is more than 1500 hv.Ceramic with high compressive strength,but low tensile strength, plasticity and toughness is poor.

Thermal properties

Ceramic materials have high melting point (mostly in above 2000 ℃), and has excellent chemical stability at high temperature;Ceramic thermal conductivity is lower than the metal material, is a good insulating material and good dimensional stability.

Electrical Properties

Most of the ceramic has good electrical insulation, so used to produce various kinds of voltage (1 kv ~ 110 kv) insulation device.Ferroelectric ceramics barium titanate (BaTiO3) has high dielectric constant, can be used in the production of capacitor, ferroelectric ceramics under the action of electric field, can also change shape, converts electrical energy into mechanical energy (with the characteristics of the piezoelectric material), can be used as an amplifier, record player, ultrasonic instrument, sonar, sound spectrograph for medical use, etc. A few ceramics has the characteristics of semiconductor, as a rectifier.

Chemical properties

Ceramic material is not easy oxidation at high temperature and under the environment of acid, alkali, salt has good corrosion resistance.

Optical properties

Ceramic materials as well as unique optical properties, can be used as solid-state laser materials, fiber materials, optical storage, etc., transparent ceramics can be used for high-pressure sodium lamp tube.Magnetic ceramics (MgFe2O4, CuFe2O4, Fe3O4) in the recording tape, record, transformer core and large computer memory element has a broad future
