1. The alumina ceramic rod has high hardness, good wear resistance, low thermal conductivity, and good chemical stability and wear resistance;
2. Alumina ceramic rods have high fire resistance, and must be able to withstand high temperatures above 1500 degrees Celsius at least;
3. The alumina ceramic rod has very good chemical stability, so it can resist acid corrosion at high temperature;
4. The strength of the alumina ceramic rod is relatively large, and the chemical stability and wear resistance are relatively good, and its density will be very high;
5. Alumina ceramic rods are inorganic, non-metallic materials. Because the entire melting point can reach degrees Celsius, it is one of the best refractory products in the entire nature.

Manufacturing Processes

1. Powder Processing: The production of alumina ceramic rods begins with the preparation of high-purity aluminum oxide powder. This powder is mixed with binders and additives to achieve the desired consistency and properties.

2. Forming: The mixed powder is then formed into rod shapes using techniques such as extrusion, injection molding, or pressing. Extrusion is commonly used for producing long, continuous rods, while pressing is suitable for shorter, precision rods.

3. Drying and Machining: After forming, the rods are dried to remove any residual moisture. They are then machined to achieve the desired dimensions and surface finish. Machining processes include grinding, lapping, and polishing.

4. Sintering: The machined rods are subjected to high-temperature sintering, where they are heated to temperatures between 1400°C and 1600°C. This process densifies the material, enhancing its mechanical and thermal properties.

5. Finishing: Post-sintering, the rods may undergo additional finishing processes, such as diamond grinding, to achieve precise dimensions and surface quality.
