Flexural Strength 200 to 400 MPa Alumina Ceramic Dielectric Strength 18 to 20 KV per mm High Strength Ceramic Components

Product Description:

Aluminum Oxide Ceramic, commonly known as Alumina ceramic, is a highly sought-after advanced ceramic material renowned for its exceptional mechanical, electrical, and thermal properties. Among the various forms of alumina ceramics, the 99% Alumina ceramic plate stands out as a premium-grade product, offering superior performance and reliability across a wide range of industrial and technological applications.

One of the most notable features of Alumina ceramic is its remarkable hardness, rated at 9 on the Mohs scale. This high hardness level makes aluminum oxide ceramic an ideal choice for applications requiring wear resistance and durability. The 99% Alumina ceramic plate, in particular, exhibits outstanding resistance to abrasion and mechanical stress, ensuring long service life even under harsh operating conditions.

In addition to its mechanical strength, aluminum oxide ceramic boasts excellent electrical properties. The breakdown voltage of this material exceeds 20 KV, highlighting its superior insulating capabilities. This high breakdown voltage makes alumina ceramic plates highly suitable for use as electrical insulators in high-voltage environments, providing safety and stability in electrical devices and components.

Another significant attribute of Alumina ceramic is its dielectric constant, which is approximately 9.6. This property indicates the material's ability to store electrical energy, making it highly valuable in electronic and electrical applications. The 99% Alumina ceramic plate, with its consistent dielectric constant, ensures stable performance in capacitors, substrates, and other electronic components where reliable insulation and dielectric properties are critical.

Thermal management is a crucial consideration in many industrial processes, and aluminum oxide ceramic excels in this regard due to its favorable thermal expansion coefficient of 8.9 x 10 ^-6 /K. This low thermal expansion rate minimizes the risk of thermal stress and cracking when the material is subjected to temperature fluctuations. As a result, alumina ceramic plates are widely used in environments with rapid heating and cooling cycles, maintaining structural integrity and dimensional stability.

The color of aluminum oxide ceramic is typically white, which not only contributes to its aesthetic appeal but also serves as an indicator of its high purity and quality. The pristine white appearance of the 99% Alumina ceramic plate reflects its minimal impurity content, ensuring consistent and reliable performance across various applications.

Alumina ceramic plates are utilized in a multitude of industries including electronics, automotive, aerospace, medical devices, and manufacturing. Their combination of high hardness, excellent electrical insulation, stable dielectric properties, and thermal stability makes them indispensable materials for components such as substrates, insulators, wear parts, and protective coatings. The 99% Alumina ceramic plate, in particular, is preferred when high purity and superior performance are required.

In summary, aluminum oxide ceramic is a versatile and high-performance material characterized by its Mohs hardness of 9, breakdown voltage exceeding 20 KV, dielectric constant of 9.6, and thermal expansion rate of 8.9 x 10 ^-6 /K. The white 99% Alumina ceramic plate embodies these attributes, offering an excellent balance of mechanical strength, electrical insulation, and thermal stability. Whether used in demanding industrial settings or advanced technological applications, alumina ceramic plates provide reliable and efficient solutions that meet the rigorous demands of modern engineering and manufacturing.
