Advanced Technical 95% Al2O3 Alumina Ceramic Block

Advanced Technical 95% Al2O3 Alumina Ceramic Block

95% alumina ceramic blocks are recognized for their exceptional mechanical and thermal properties, making them a popular choice in various industrial applications. Composed primarily of aluminium oxide with a purity of 95%, these ceramic blocks exhibit high hardness, wear resistance, and dimensional stability. They also offer excellent high-temperature and corrosion resistance, which is crucial for applications where the material may be exposed to extreme conditions. Additionally, 95% alumina ceramic blocks have a competitive price point compared to other materials with similar properties, such as 92% alumina, making them an economically viable option for many businesses. Common forming technologies for these blocks include dry pressing, cold isostatic pressing with green machining, slip casting, and hot pressing, which allow for the creation of complex shapes and designs.

The applications for 95% alumina ceramic blocks span across numerous industries due to their unique combination of properties. They are widely used in the manufacturing of heat sinks, discs, insulators, and igniters, where their ability to withstand high temperatures and resist corrosion is highly valued. In the electronics industry, these ceramic blocks serve as substrates for mounting or fabricating MEMS devices, thanks to their low dielectric loss and high thermal conductivity. Furthermore, their low specific weight and high strength make them ideal for use in aerospace and automotive applications, where lightweight yet durable materials are essential. The dimensional stability of 95% alumina ceramic blocks also makes them suitable for precision engineering and components that require tight tolerances. Overall, these blocks provide a reliable and cost-effective solution for a broad range of technical applications.
