Ceramic balls have replaced metal balls in many applications, such as industrial ball bearings, due to their superior strength, durability, and resistance to corrosion. As the video shows, manufacturers create ceramic inert support media in many sizes. Using raw materials, such as silicon nitride and zirconia oxide, these ceramic products offer incomparable durability and a wide range of applications.
The multi-stage production process starts with materials acquisition. The manufacturers obtain high-quality raw materials, such as zirconia powder and silicon nitride powder. Additives to these pure ingredients enhance durability.
Inserted into forms while in liquid or powdered form, the balls take shape. Forming techniques include slip casting, injection molding, and pressing. After the forming phase, the balls go through the sintering process.
Sintering refers to cooking the material at high temperatures. Sintered in an industrial furnace, exposure to this heat brings about changes in the materials that increase density and add strength. As a final step, the ceramic balls undergo finishing. First ground, then polished, they take their final shape. Manufacturers add a coating to bring the product to the required quality standards.
Besides their use as ball bearings, you can find these ceramic balls in wire drawing dies, balls and rollers in valves, cutting tools, medical prosthetics, and dental implants. They also have heavy industrial uses, including insulators in electronics and thermocouple protective tubes. Their tough, abrasion-resistant design helps them last longer than other options, as does their low thermal expansion coefficient.
