Description of high purity ceramic alumina rods
We offer numerous high purity alumina ceramic rods ranging from 75% ~ 99.8%. These al2o3 ceramic rods are commonly shaped via extrusion, dry pressing, hot pressing, ISO pressing and so on.
We are capable of dealing with small-size to large-size, the min. diameter can be 1 mm, the largest diameter can be 50 mm and the max. length can be up to 1000 mm. In order to achieve some special needs in the application, these alumina ceramic rods could be fine ground, polished, or glazed with our in-housing equipment. Furthermore, customized shape of alumina ceramic rods are available.
In addition, we provide many selection of different materials of ceramic rods, mainly including zirconium oxides, Silicon nitride, Silicon carbide and steatite. Whenever you are looking for a reliable partner for ceramic rods, please feel free to contact us.
