Ceramic Industrial Packing Ball Inert Ceramic Alumina Support Media Zirconia Balls
Description
Product name: high temperature resistant and high hardness zirconia ceramic ball
Material: Zirconia ceramic ball
Specification: 0.8mm-30mm
Surface treatment: polished, mirrored
Zirconia (ZrO2): It has high strength and toughness at room temperature, good wear resistance, high temperature resistance and corrosion resistance, high rigidity, non-magnetic conductivity, and electrical insulation. The strength and hardness of the zirconia ceramic ball is almost unchanged at 600°C. Its density is 6.00g/cm3, and its thermal expansion rate is close to that of metal.
The advantages of ceramic balls as follows:
1. High hardness: the Vickers hardness of ordinary Gcr15 bearing steel is 800HV, while the hardness of the zirconia ceramic ball is above 1700HV.
2. High wear resistance: Take our company's process of processing products as an example, ordinary steel ball milling (with a margin of one millimeter) takes about 2-4 hours, while silicon nitride ball processing requires at least 150-200 hours.
3. Corrosion resistance: The stability of ceramic materials is excellent, especially silicon nitride balls, which hardly react with any substances. They are widely used in industries such as petroleum, chemical, food and other industries that need to contact strong oxidants and strong reducing agents. .
4. High temperature resistance: The ceramic ball has to experience thousands of degrees Celsius high temperature and great pressure during the sintering process. Its internal molecular structure is very stable and the arrangement is very dense. This makes its thermal expansion coefficient very low, and the change of temperature has almost its structure size. There is no impact. The working temperature of the ceramic ball can reach 1200 degrees Celsius or even higher, and the low temperature has little effect on it, so it is widely used in the aerospace field.
5. Light weight: The weight of ceramic balls is only 50%-60% of ordinary steel balls, which is very promising in the field of bearings and aerospace.
6. Self-lubricating: The ceramic ball itself has good self-lubricating performance and high processing precision. It can reach G5 and G10 grades. The ceramic balls are wear-resistant, stable in structure and not easy to deform, so they can be fine processed and applied to many special industries.
7. Insulation: Ceramic has good insulation effect.
Application
The produced high-purity zirconia beads (TZP Ceramics beads) are the most ideal grinding media. It has been widely used in the ultra-fine grinding and dispersion of materials in industries such as non-metallic minerals, coatings, inks, paints, dyes, titanium dioxide, pesticides, and magnetic materials.
