Products Description

Electronic and Dielectric Ceramics is a class of advanced ceramic materials with a wide range of applications in the electronics industry. And due to the increasing demand for the development of IoT, sensors, actuators, antennas, filters, and baluns in a range of industries such as telecommunications, medical, automotive, aerospace applications, Electronic and Dielectric ceramics plays an important role in microelectronic components due to their unique electrical properties, such as high dielectric constant, low dielectric loss, and temperature stability. At the same time, electronic and dielectric ceramics provide low signal loss and high dielectric constant, which is beneficial for RF and microwave circuits, provides efficient heat dissipation for LED modules, and provides thermal stability for power electronics.

Ceramic materials with a dielectric constant of 4 are low dielectric constant dielectric ceramics, which are mainly used in high-frequency electronic devices and microwave communications. Hexagonal boron nitride (h-BN) has a dielectric constant of about 4.0-4.5, very low dielectric loss (tan6<0.0002) and excellent high frequency stability. It can be used in high-frequency substrates: 5G/6G communication filters, antenna substrates, utilizing its low signal delay characteristics. Microwave windows: wave-transparent materials for radar systems, combining low dielectricity and weather resistance.

Ceramics with a dielectric constant of 10.5 are medium dielectric ceramics, with 2MgO-Ti0z (magnesium orthotitanate) or MgO-TiO: (magnesium metatitanate) as the main crystalline phase, and with the addition of fluxes such as zn0 and Caf:, the dielectric constant is adjusted to around 10.5. The dielectric constant of the titanium-zirconium composite system was adjusted by the ratio of components, and the dielectric constant of around 10.5 was found to be both mechanically strong and frequency stable.

Can be used in filters, resonators, etc. to meet the dielectric stability requirements of 5G/6G communications. Multilayer Ceramic Capacitors (MLCCs): Used as a dielectric layer in the mid-frequency band to balance the need for miniaturization of capacity and size.
