Product Description:

The 99% Alumina ceramic plate is a high-performance material widely used in various industrial applications due to its exceptional physical and electrical properties. This Alumina ceramic is renowned for its outstanding combination of mechanical strength, electrical insulation, and chemical stability, making it an ideal choice for demanding environments where durability and reliability are critical.

One of the key characteristics of this Alumina ceramic plate is its dielectric constant of 9.6. This property indicates the material's ability to store electrical energy in an electric field, making it highly suitable for use in electronic components and insulation applications. The high dielectric constant ensures efficient performance in capacitors, substrates, and other electronic devices where stable dielectric properties are essential.

In addition to its excellent dielectric properties, this Alumina ceramic boasts an insulation resistance greater than 10 ¹² Ohm-cm. Such a high level of insulation resistance highlights its superior ability to resist electric current flow, which is crucial for preventing electrical leakage and ensuring safety in electrical and electronic systems. This makes the 99% Alumina ceramic plate an excellent material for insulating components in power electronics, telecommunications, and high-voltage applications.

From a mechanical standpoint, the Alumina ceramic exhibits remarkable strength characteristics. Its tensile strength ranges from 200 to 400 MPa, providing robust resistance to pulling and stretching forces. This tensile strength ensures that the ceramic plate can withstand mechanical stresses during manufacturing and in-service conditions without cracking or breaking. Furthermore, the compressive strength of the Alumina ceramic exceeds 3000 MPa, demonstrating its exceptional ability to endure high compressive loads. This makes the material highly suitable for structural components, wear-resistant parts, and applications subjected to heavy mechanical pressure.

The 99% Alumina ceramic plate is characterized by its pure white color, which is a result of its high alumina content and minimal impurities. This white color not only enhances the aesthetic appeal but also indicates the material's purity and quality. The clean, white appearance is often preferred in applications where visual inspection or identification is necessary, such as in medical devices or laboratory equipment.

Alumina ceramic, in general, is known for its excellent chemical inertness and resistance to corrosion. The 99% Alumina ceramic plate maintains these properties, making it highly resistant to acids, alkalis, and other aggressive chemicals. This chemical stability ensures a long service life even in harsh chemical environments, which is why Alumina ceramic is commonly used in chemical processing, pharmaceuticals, and food industry applications.

Moreover, the Alumina ceramic’s excellent thermal stability and high melting point allow it to perform reliably under high-temperature conditions. This thermal resistance, combined with its mechanical and electrical properties, makes it indispensable in applications such as furnace components, heat exchangers, and thermal insulators.

In summary, the 99% Alumina ceramic plate offers a superior combination of a dielectric constant of 9.6, insulation resistance exceeding 10 ¹² Ohm-cm, tensile strength between 200 and 400 MPa, compressive strength greater than 3000 MPa, and a pristine white color.
