Compressive Strength Greater Than 3000 MPa Alumina Ceramic Providing Outstanding Wear Resistance And Mechanical Strength

Product Description:

Aluminum Oxide Ceramic, commonly referred to as alumina ceramic, is a highly versatile and widely used advanced ceramic material known for its exceptional mechanical, electrical, and thermal properties. Among its many forms, the alumina ceramic substrate and alumina ceramic plate are particularly notable for their robust performance in demanding industrial applications. The 99% alumina ceramic plate, in particular, is renowned for its purity and superior characteristics, making it an ideal choice for a broad range of uses.

One of the most impressive attributes of aluminum oxide ceramic is its outstanding compressive strength, which exceeds 3000 MPa. This remarkable strength allows alumina ceramic substrates and plates to withstand high pressure and mechanical stress without deformation or failure. Such high compressive strength makes these materials highly suitable for structural components, wear-resistant parts, and protective covers in various manufacturing and engineering environments.

In addition to its mechanical strength, aluminum oxide ceramic exhibits excellent electrical insulation properties. The dielectric strength of this material ranges between 18 to 20 KV/mm, enabling it to resist high voltages without electrical breakdown. This characteristic is crucial for alumina ceramic substrates used in electronic and electrical applications, where reliable insulation and high voltage resistance are paramount. The dielectric constant of aluminum oxide ceramic is approximately 9.6, providing stable and predictable performance in capacitors, insulators, and other electronic components.

Thermal management is another area where aluminum oxide ceramic excels. With a thermal expansion coefficient of 8.9 x 10 ^-6 /K, alumina ceramic plates and substrates maintain dimensional stability under temperature variations, reducing the risk of cracking or warping during thermal cycling. This property is essential for applications involving rapid heating and cooling or exposure to fluctuating temperatures. Furthermore, aluminum oxide ceramic offers a thermal conductivity in the range of 25 to 35 W/mK, which facilitates efficient heat dissipation. This combination of thermal expansion and conductivity makes 99% alumina ceramic plates highly effective in thermal management solutions, such as heat sinks, thermal barriers, and substrates for power electronics.

The purity of the alumina ceramic plays a critical role in determining its overall performance. The 99% alumina ceramic plate contains a high concentration of aluminum oxide, which enhances its mechanical strength, electrical insulation, and thermal properties. This high purity level ensures consistent quality and reliability, making it suitable for precision applications in the electronics, aerospace, automotive, and medical industries.

Moreover, alumina ceramic substrates and plates are chemically inert and resistant to corrosion, which extends their service life even in harsh environments. They can withstand exposure to acids, alkalis, and other aggressive chemicals without degradation. This chemical stability, combined with their wear resistance and hardness, makes alumina ceramic an excellent material choice for protective coatings, seals, and components exposed to abrasive conditions.

In summary, aluminum oxide ceramic, particularly in the form of alumina ceramic substrates and 99% alumina ceramic plates, offers a unique combination of superior compressive strength, excellent dielectric properties, and effective thermal management capabilities. Its high mechanical strength (>3000 MPa), dielectric strength (18-20 KV/mm), dielectric constant (9.6), controlled thermal expansion (8.9 x 10 ^-6 /K), and good thermal conductivity (25-35 W/mK) make it an indispensable material in modern technology and industry. Whether used in electronics, machinery, or chemical processing, aluminum oxide ceramic continues to deliver outstanding performance and reliability, meeting the rigorous demands of advanced applications worldwide.
