Types of Electronic & Dielectric Ceramics
 

The electronic & dielectric ceramics produced by our company mainly include the following types:

Insulation Parts Ceramic

Ceramic insulation parts are known for their excellent electrical insulation capabilities. They prevent the passage of electric current, ensuring safety and reliable operation in electrical systems.

Dielectric Ceramics

Electronic and Dielectric Ceramics is a class of advanced ceramic materials with a wide range of applications in the electronics industry.

 

 
Advantages of Electronic & Dielectric Ceramics
 
01/

Hardness
Although ceramic materials are derived from powders, they possess remarkable hardness. In fact, dielectric ceramics are approximately four times harder than stainless steel. This exceptional hardness contributes significantly to their durability and long-term performance.

02/

Wear Resistance
Along with their exceptional hardness, dielectric ceramics maintain their finish and appearance over time. Their wear resistance and hardness work together to provide resilience and durability, which are crucial for long-term sustainability.

03/

Mechanical Properties
Components designed to protect electrical wiring must retain their mechanical properties under various conditions. dielectric ceramics are highly effective at preserving these properties, ensuring consistent performance and reliability.

04/

Dielectric Strength
This quality is a key reason dielectric ceramics are selected for various electrical wiring and circuits. Their high dielectric strength and low electrical loss ensure outstanding performance under a range of conditions.

05/

Resistance to Corrosion
Because dielectric ceramics contain no metal, they are resistant to rust and corrosion. This property allows them to be used on fence posts, power line crossarms, and other outdoor electrical installations without being affected by environmental conditions.

06/

Thermal Conductivity
Dielectric ceramics typically exhibit increased conductivity with rising temperatures, while simultaneously reducing energy consumption.

FAQ

 

Q: What are dielectric ceramics?

A: Dielectric ceramics are ceramic materials with high dielectric constant and low dielectric loss. They are mainly used to manufacture electronic components such as capacitors and microwave devices, and store electrical energy through polarization.

Q: What are the dielectric properties of ceramics?

A: Ceramics exhibit high dielectric constant values (high permittivity or high ability to polarize and hold charge) such as SiNx with 4 < k < 10, Ta2O5, Al2O3, ZrO2, HfO2 with 10 < k < 100, and PZT with k < 10.

Q: Is ceramic a good dielectric?

A: Ceramics with high breakdown voltages (dielectric strength) and good temperature stability are the preferred dielectric for capacitors and memory cells.

Q: What is the difference between dielectric ceramics and ordinary ceramics?

A: Dielectric ceramics focus on dielectric properties (such as high dielectric constant and low loss), while ordinary ceramics focus more on mechanical or thermal properties, and their application scenarios are different.

Q: What are the common causes of dielectric ceramic cracking?

A: Mismatched thermal expansion coefficients (such as metallization layer and ceramic substrate), too fast cooling rate during sintering, agglomeration of raw material powder, etc.

Q: Why does dielectric ceramics increase loss at high frequencies?

A: Polarization relaxation intensifies under high-frequency electric fields, and ion or electron migration produces energy loss, so low-loss microwave dielectric ceramic materials need to be selected.
