Breakdown Voltage Over 20 KV Alumina Ceramic Material Offering Compressive Strength Greater than 3000 MPa Ideal for High Voltage Insulation

Product Description:

The Aluminum Oxide Ceramic product is a highly durable and versatile material widely recognized for its exceptional mechanical and electrical properties. Manufactured primarily from high-purity alumina, this product is available in various grades including the 99% Alumina ceramic plate and the 95% Alumina ceramic plate, catering to diverse industrial applications where reliability and performance are paramount. These alumina ceramic substrates are engineered to offer outstanding strength, wear resistance, and excellent thermal stability, making them ideal for advanced technological uses.

One of the key attributes of the Aluminum Oxide Ceramic product is its impressive flexural strength, which ranges between 200 and 400 MPa. This high flexural strength ensures that the ceramic plates and substrates can withstand significant mechanical stress and bending forces without fracturing, making them suitable for use in structural components, protective armor, and high-load bearing applications. The strength also contributes to the longevity and durability of the product, reducing the need for frequent replacements and maintenance.

In addition to its mechanical robustness, the Aluminum Oxide Ceramic product exhibits excellent dielectric strength, ranging from 18 to 20 KV/mm. This high dielectric strength makes the alumina ceramic substrate an excellent electrical insulator, capable of enduring high voltage stress without electrical breakdown. As a result, these ceramics find widespread use in electronic and electrical industries for components such as insulators, substrates for electronic circuits, and insulating supports in high-voltage equipment. The combination of high dielectric strength and thermal stability enhances the overall performance of electronic devices, ensuring safety and efficiency.

The material properties of the Aluminum Oxide Ceramic product are further characterized by a Poisson's ratio of approximately 0.25. This value indicates the material's tendency to expand or contract laterally when subjected to longitudinal stress, providing insight into its deformation behavior under mechanical loads. Such information is crucial for engineers and designers who need to predict and accommodate dimensional changes in precision components and assemblies.

Another significant mechanical property of this alumina ceramic substrate is its Young’s modulus, which falls within the range of 200 to 400 GPa. This high modulus of elasticity signifies the material’s stiffness and resistance to elastic deformation under applied stress. The elevated Young’s modulus ensures that the ceramic plates maintain their shape and structural integrity even under demanding environmental and operational conditions. This characteristic is particularly valuable in applications requiring precise dimensional stability, such as in aerospace, automotive, and electronic sectors.

The Aluminum Oxide Ceramic product, including both 99% and 95% alumina ceramic plates, is also noted for its excellent thermal conductivity and chemical inertness. These properties allow the ceramic substrates to perform reliably in high-temperature environments and corrosive conditions without degradation. The material’s resistance to thermal shock and chemical attack makes it an optimal choice for use in kiln furniture, furnace linings, and other high-temperature industrial equipment.

In summary, the Aluminum Oxide Ceramic product is a superior material combining high flexural strength, excellent dielectric strength, a balanced Poisson's ratio, and a high Young’s modulus. Its availability in grades such as 99% Alumina ceramic plate and 95% Alumina ceramic plate offers flexibility in meeting specific industrial requirements. As an alumina ceramic substrate, it is indispensable in numerous applications ranging from electronics and electrical insulation to structural components and thermal management systems. The robust mechanical and electrical properties of this product ensure long-lasting performance, making it a trusted choice for engineers and manufacturers worldwide.
