Alumina Rod
Alumina rods are cylindrical structures made of alumina ceramic material, also known as aluminum oxide (Al2O3). Alumina is a highly durable and heat-resistant material that is widely used in various industrial applications, such as electrical insulation, refractory lining, and high-temperature processing.
Alumina rods are typically produced through a process of shaping and sintering of alumina powder, resulting in a dense and uniform ceramic structure. They can vary in size, diameter, and length depending on the intended use and application.
Alumina rods have excellent mechanical and electrical properties, including high strength, hardness, and thermal conductivity. They are also resistant to chemical corrosion, making them suitable for use in harsh and corrosive environments.
Alumina rods are commonly used in laboratory and industrial settings for applications such as stirring, mixing, and supporting of high-temperature samples. They are also used in heating elements, thermocouple protection tubes, and other high-temperature applications where high strength and durability are required.
Overall, alumina rods are a reliable and versatile material that offer excellent performance and longevity in a variety of high-temperature and corrosive environments.
