Advantages of alumina industrial ceramic rods
Alumina rod is wear-resistant, corrosion-resistant, and heat-resistant. Alumina rod overall quality assurance (factory certified by ISO9001), no material adulteration, and enhanced toughness. Non toxic, odorless, and can be used without cleaning. It is not easy to break in industrial use (hardness 9 Mohs), and the raw materials can withstand high temperatures when stirred for production, making it convenient to use.
Applications of alumina industrial ceramic rods
1. Alumina rods are used as insulation supports and structural components in industrial furnaces and kilns.
2. In high-temperature measurement, alumina rods serve as protective sheaths for thermocouples.
3. Alumina rods are used in various electronic components and devices as insulators.
4. In high-voltage applications, such as power transmission and distribution system.
5. Alumina rods are used in reactors and containment vessels.
6. In the petrochemical industry, alumina rods serve as supports for catalysts used in various chemical reactions, providing a stable and inert environment that enhances catalyst performance.
7. Alumina rods are used in machinery and equipment as wear-resistant components.
8. In the manufacturing industry, alumina rods are utilized in cutting and machining tools due to their hardness and ability to maintain sharpness over prolonged use.
Quality testing standards
1. Visual inspection of the rod for any signs of damage or irregularities.
2. Measurement of the length, width, and thickness of the rod to check for accuracy.
3. Checking for any leaks or pinhole defects in the rod.
4. Verification of the material and chemical composition of the rod.

FAQ
A1. Ceramics are non-metallic, inorganic materials that are typically composed of a combination of metallic and non-metallic elements. Alumina is a type of ceramic oxide, specifically an oxide of aluminum. It is widely used in various applications due to its excellent mechanical, thermal, and electrical properties.
A2. Because of their excellent chemical stability, alumina rods are used widely in acid-resistant pump impellers, pump bodies, acid-carrying pipe linings and valves. Alumina rods are used in the manufacture of textile wear parts and knives. This is due to their extreme hardness and wear resistance.
A3. Alumina rods is a very hard ceramic that is excellent at resisting abrasion and is ideal for wear-resistant inserts or products.
