Alumina rods

Advantages of Alumina rods

1. The alumina rods has strong hardness, second only to diamond in hardness.

2. Alumina rods have the advantages of wear resistance, corrosion resistance, and resistance to impacts,

3. Alumina rods are non-toxic and odorless, suitable for use as machine parts in the medical and food industries.

4. High temperature resistance, long-term use at 1600 ℃, short-term use at 1800 ℃.

5. Alumina rods have electrical insulation properties and can be used as insulating components for electronic experiments.

Applications of Alumina rods

1. Mechanical aspect. Alumina rods widely used for cutting hard materials.

2.Industrial aspect. Alumina rods widely used for industrial valve sealing bearings, sealing rings, ball valves, etc.

3. In terms of electronics and power. Alumina rods widely used for electrical insulation ceramic parts, electronic materials, magnetic materials, etc.

4.In terms of medicine. Alumina rods more commonly used for manufacturing artificial bones, joints, teeth, etc

5. In terms of architectural and sanitary ceramics. Alumina rods widely used for grinding media, rods, ceramic protective tubes, and alumina refractory materials.

Clean alumina rods

1.Firstly, place the alumina rod into a mild detergent solution.

2. Gently scrub the alumina rods with a brush.

3. Rinse the rod with clean warm water to ensure the removal of residue.

4. Use a clean and soft cloth to dry the alumina rod and check if it has been cleaned thoroughly.

5.If the stains are severe, please repeat the cleaning process until the alumina rod is completely clean.

Alumina rods

Slip casting moulding: Inject the prepared slurry into the gypsum mold and let it stand for a period of time to allow the gypsum mold to absorb moisture. The slurry forms a uniform body on the inner wall of the mold.
Isostatic pressing: During the isostatic pressing procedure, binders are blended with the ceramic powder. As a result of this process, the powder transforms into freely flowing granules that can effortlessly fill the molds.
Extrusion moulding: Suitable for long tube products, the powder is extruded into shape through an extruder.
