Zirconia beads, called TZP, also called zirconium beads, 95 zirconium beads, yttrium stabilized zirconia beads, zirconia balls, zirconia ceramic balls, Zirconia Ceramic Grinding Media, etc. Use micron/sub-nanometer zirconia powder as raw material, sintered by medium-high temperature by sintering method. It has good spherical gloss, high density, high hardness, low abrasion and high grinding efficiency. It is the highest quality grinding media at present.

3 . Main features:
•95 zirconia beads have good roundness, smooth surface, high density, and good hardness, making them a perfect and fine spherical grinding medium;
•Low wear (ppm level), minimal wear on equipment, making it the best grinding medium..
4 . The research and mass production of 95 zirconia beads marks our factory's achievement of import substitution in the field of high-end ceramic grinding media. Its technological innovation is reflected in three major dimensions:
1. Breakthrough in raw materials and preparation process: Using nanoscale zirconia powder (particle size<50nm) as raw material, nanoscale control of grain size (average grain size ≤ 0.5 μ m) is achieved through isostatic pressing and vacuum sintering technology. Compared with traditional rolling process, this technology reduces the porosity inside the bead to less than 0.1%, and the compressive strength exceeds 1000N (1mm bead), reaching the level of international first-line brands. According to testing conducted by a certain ceramic research institute, its impact fatigue life has increased by 15% compared to imported products, filling the technological gap in high-end bead materials in China.
2. Construction of an intelligent quality control system: The production process introduces a machine vision inspection system to conduct a full inspection of the roundness (>= 99%), surface roughness (Ra <= 0.2 μ m), and particle size tolerance (± 0.02mm) of each bead, with a failure rate controlled below 0.05%. By analyzing the correlation model between process parameters and product performance through big data, dynamic optimization from raw material ratio to sintering curve is achieved, which improves batch stability to over 98% and meets the strict consistency requirements of high-end customers.
3. Green manufacturing and circular economy: The production process adopts a closed water circulation system, with a water resource reuse rate of 85%; The introduction of waste heat recovery devices in the sintering process reduces energy consumption by 22%. In addition, waste beads can be regenerated through chemical methods, with a material recovery rate of over 90%, significantly reducing industrial waste emissions compared to the disposable mode of traditional steel beads. A certain new energy enterprise has calculated that the large-scale use of this pearl can reduce solid waste emissions by 300 tons per year, reduce comprehensive costs by 18%, and achieve a win-win situation of economic and environmental benefits.
