Hangzhou JWG Technology Co.Ltd | Updated: May 18, 2017


Functional ceramics refers to the use of their non-mechanical properties of materials, such materials usually have one or more functions. such as electricity, magnetism, light, heat, chemistry, biology and other functions, as well as coupling functions such as piezoelectric, piezoelectric, Functional Ceramics thermoelectric, electro-optic, acoustic and light, magnetic and other functions. Functional ceramics has been widely used in the fields of energy development, space technology, electronic technology, sensing technology, laser technology, photoelectron technology, infrared technology, biotechnology, environmental science and so on. 1. Electronic ceramics including insulating ceramics, dielectric ceramics, ferroelectric ceramics, piezoelectric ceramics, pyroelectric ceramics, sensitive ceramics, magnetic materials and conductive, superconducting ceramics. According to the dielectric characteristics of capacitor ceramics, it is divided into 6 categories: high-frequency temperature compensation type dielectric ceramics, high frequency temperature stable dielectric ceramics, low-frequency high dielectric coefficient Functional Ceramics type dielectric ceramics, semiconductor type dielectric ceramics, laminated capacitor ceramics, microwave dielectric ceramics. Microwave dielectric ceramics are characterized by high permittivity, Functional Ceramics low dielectric loss, and small resonant frequency coefficient, which are widely used in microwave communication, mobile communication, satellite communication, broadcast television, radar and other fields.


The classification and development foreground of functional ceramic materials The functional ceramics is the material that uses its non-mechanical properties mainly when applied, and this kind of material usually has one or more functions. such as electricity, magnetism, light, heat, chemistry, Functional Ceramics biology and other functions, as well as coupling functions such as piezoelectric, piezoelectric, thermoelectric, electro-optic, acoustic and light, magnetic and other functions. Functional ceramics has been widely used in the fields of energy development, space technology, electronic technology, sensing technology, laser technology, Functional Ceramics photoelectron technology, infrared technology, biotechnology, environmental science and so on. 1. Electronic ceramics including insulating ceramics, dielectric ceramics, ferroelectric ceramics, piezoelectric ceramics, pyroelectric ceramics, sensitive ceramics, magnetic materials and conductive, superconducting ceramics. According to the dielectric characteristics of capacitor ceramics, it is divided into 6 categories: high-frequency temperature compensation type dielectric ceramics, high frequency temperature stable dielectric ceramics, low-frequency high dielectric coefficient type dielectric ceramics, semiconductor type dielectric ceramics, laminated capacitor ceramics, microwave dielectric ceramics. Functional Ceramics Microwave dielectric ceramics are characterized by high permittivity, low dielectric loss, and small resonant frequency coefficient, which are widely used in microwave communication, mobile communication, satellite communication, broadcast television, radar and other fields.

2. Thermal, optical ceramic heat-resistant ceramic, thermal insulation ceramics, thermal conductivity ceramics is the main application of thermal ceramics. Among them, heat-resistant ceramics are mainly Al2O3, MgO, SIC, etc., because they have high temperature stability, can be used as refractories to the metallurgical industry and other industries. Thermal insulation ceramics have good insulation effect and are widely used in various fields. Ceramic materials in optics include absorbing ceramics, ceramic optical signal generators and optical fibers, the use of ceramic optical coefficient characteristics in life everywhere, such as coatings, ceramic glaze. Functional Ceramics In the nuclear industry, the use of heavy ion ceramics including PB, barium, and the absorption and fixation of nuclear radiation waves is widely used in waste disposal. Ceramics are also important materials for solid-state laser generators, with ruby lasers and yttrium garnet lasers. Optical fibre is the main transmission medium of modern communication signal, with low signal loss, high fidelity, large capacity and other characteristics than metal signal transportation. Transparent alumina ceramics is a typical representative of optical ceramics, in the manufacturing process of transparent alumina, the key is the volume diffusion of alumina as the sintering mechanism of grain growth process, in the raw materials to add appropriate additives such as magnesium oxide, can inhibit the growth of grain. It can be used as melting glass crucible, infrared detection window materials, lighting fixtures, and also for the manufacture of electronic industry in the IC substrate and so on.
