Breakdown Voltage Greater Than 20 KV Alumina Ceramic Providing Tensile Strength 200 to 400 MPa Used in Insulating Parts

Product Description:

Aluminum Oxide Ceramic, commonly known as alumina ceramic, is a high-performance material widely used in various industrial applications due to its remarkable mechanical, electrical, and thermal properties. One of the key forms of this material is the alumina ceramic substrate, which serves as an essential component in electronics, electrical insulation, and thermal management systems. With its excellent combination of strength, durability, and insulation capabilities, aluminum oxide ceramic is a preferred choice for demanding environments.

The 95% alumina ceramic plate is particularly popular because it offers an optimal balance between purity and performance. This composition ensures superior mechanical strength and thermal stability, making it suitable for applications requiring both toughness and resistance to high temperatures. The 95% alumina ceramic plate has a tensile strength ranging between 200 and 400 MPa, which provides excellent resistance to mechanical stresses and ensures long-lasting durability under demanding conditions.

Flexural strength is another critical attribute of aluminum oxide ceramic, with values also in the range of 200 to 400 MPa. This high flexural strength allows the alumina ceramic plate to withstand bending and flexing forces without cracking or breaking, making it ideal for structural applications and components that experience dynamic loading. The resilience of the alumina ceramic substrate under mechanical stress contributes significantly to its widespread use in the electronics and automotive industries.

In addition to its mechanical properties, aluminum oxide ceramic exhibits exceptional electrical insulation characteristics. The insulation resistance of the material exceeds 10¹² Ohm-cm, making alumina ceramic substrates highly effective at preventing electrical conduction and ensuring safety in high-voltage environments. This outstanding insulation resistance is crucial for electronic devices, sensors, and other equipment where electrical isolation is necessary to maintain performance and prevent short circuits.

Thermal properties are equally impressive for aluminum oxide ceramic. The thermal expansion coefficient of 8.9 x 10⁻⁶/K ensures minimal dimensional changes when exposed to temperature fluctuations, providing excellent thermal stability. This low thermal expansion minimizes the risk of cracking and deformation during rapid heating or cooling cycles, which is particularly important in applications involving thermal cycling or high-temperature operations.

Thermal conductivity is another vital aspect of the 95% alumina ceramic plate, with values ranging from 25 to 35 W/mK. This relatively high thermal conductivity allows the alumina ceramic substrate to efficiently dissipate heat, preventing overheating and enhancing the reliability of electronic components and systems. The ability to conduct heat effectively while maintaining electrical insulation makes aluminum oxide ceramic an ideal material for heat sinks, substrates, and insulating components in power electronics and LED manufacturing.

Overall, aluminum oxide ceramic, especially in the form of the alumina ceramic plate and alumina ceramic substrate, offers a unique combination of high tensile and flexural strength, outstanding electrical insulation, low thermal expansion, and excellent thermal conductivity. These attributes make the 95% alumina ceramic plate a versatile and reliable material for numerous industrial applications, including electronics, automotive, aerospace, and mechanical engineering. Its durability, thermal stability, and electrical insulating properties ensure optimal performance and longevity, meeting the rigorous demands of modern technology and manufacturing processes.
