Dongguan Ming Rui Ceramic Technology Co., Ltd
High frequency porcelain is used for various types of high frequency insulators, dial switch ceramic shaft, ceramic bushings, resistance matrix and sealed shell and other electronic components.
It has the characteristics of high thermal insulation, good chemical stability, good compressive strength and so on.
Ceramic materials for installation, fixing, protection and insulation of electronic equipment.
The main types are talc, alumina, magnesium olivine, boron nitride, and corundum mullite.
It is characterized by high insulation resistance, low dielectric constant, low dielectric loss, high mechanical strength, good thermal conductivity, small coefficient of thermal expansion, good chemical stability and thermal stability.
High frequency porcelain is mainly composed of α-alumina, accounting for more than 75% of all kinds of ceramics.
It has excellent mechanical and electrical properties and is one of the most widely used high frequency insulating ceramics.
It can be used as high power insulation element of UHF and vacuum electronic devices.
It can be used to manufacture the ceramic shell of vacuum condenser, the window of microwave ceramic element, the ceramic substrate with talc ceramics and natural minerals as the main raw materials, so that the microcrystalline stone as the main crystalline phase, excellent birefringence and other multimedia ceramics.
Risk, information, claims and collection features and low prices.
Disadvantages are high thermal expansion coefficient, poor thermal stability, low strength.
Compared with high aluminum talc ceramics, talc ceramics are widely used in the manufacture of switches, sockets, adjustable capacitor components and shafts, ceramic plates, inductance coil frames, etc.
High frequency porcelain is insulating ceramic, also known as ceramic.
It is mainly used for the installation, fixing and protection of electronic equipment, providing insulation support for current carrying conductors and ceramics on various integrated electric subgrade boards.
Low dielectric constant, low dielectric loss, high mechanical strength, high insulation strength, insulation resistance and thermal conductivity.
With the development of electronic industry, high aluminum ceramics mainly include dielectric ceramics, talc ceramics, especially thick film, thin film circuit and microwave integrated circuit.
Higher requirements are put forward for ceramic packaging and substrate.
There are many new varieties of beryllium oxide ceramics and boron nitride ceramics.
The development of aluminum nitride ceramics and the research of silicon carbide ceramics have the characteristics of high thermal conductivity.
