Product Description

Product Description:

Valves And Bearings With High Durability And Abrasion-Resistant

Alumina ball is a type of aluminum ball produced from the raw materials of bauxite, roll powder, alumina, and high temperature calcined αalumina powder. These ingredients are mixed, ground, and formed into a pulp, clay, and molded. After drying, they are then fired in a sintering process. It is mainly used as a grinding medium and is widely used as a balle stone.



Alumina oxide balls are well-known for providing excellent performance in high-temperature environments. Their dimensional stability can be maintained even in temperatures up to 3180 ºF. Moreover, these ceramic balls stand out with their outstanding wear resistance, making them suitable for abrasive and high-wear applications. Besides, alumina oxide balls are noteworthy for their high level of corrosion resistance, as they can tolerate various salt solutions, water, and plenty of chemical acids.

Furthermore, alumina oxide is characterized by excellent electrical insulation properties. That is why alumina oxide balls are often employed for a wide range of electrical components, such as spark plugs and insulators. Most importantly, these balls show a remarkable level of chemical stability, especially when used in acidic and basic environments.

Alumina balls are widely used for a variety of applications. They are commonly employed as grinding and milling media in ball mills and grinding jars, used to disperse materials. They are also used for catalysts support, as they provide a stable substrate for the catalytic material and can be crafted to various shapes and sizes. In chemical processing, alumina balls are used as fillers, and as support materials for catalysts to maximize the efficiency of chemical reactions.

In addition, alumina balls are used as substrates for micro-electronics and electronic components due to their excellent electrical insulation properties. Ceramic bearings are also the product of choice, due to its high hardness, wear resistance, and low coefficient of thermal expansion. Moreover, alumina balls are also used as heat exchangers and transfer media due to its excellent thermal stability. In refractory applications, alumina balls are often transformed into furnace linings, crucibles, and casting molds due to its high melting point and chemical stability. The same properties help them serve as abrasion-resistant linings for protecting pipelines and tanks against wear.

Moreover, alumina balls provide excellent electrical and thermal insulation, and are used as insulators in high-voltage and high-temperature environments. In water treatment systems, alumina balls act as filtration media due to its hydrophilic properties and ability to remove impurities from water. Finally, alumina balls are also used in biomedical applications, such as for orthopedic implants, dental implants, and prosthetics, owing to its biocompatibility and bone-bonding properties.
