YTZP yttria zirconia beads are made of high-grade and nanometer Yttria Stabilized Zirconia (YSZ) which is proudly produced by our own facility in large and homogenous batches. This advanced precursor material guarantees excellent mechanical properties, outstanding wear resistance and good corrosion resistance. This high density bead is used to achieve maximum milling results at minimum product contamination rates.

Until now, CHEMCO® YTZP zirconia beads are successfully being used in all modern types of mills, which include vertical mills, horizontal mills, agitated media mills, stirred media mills, such as IsaMill, Metso Vertimill®, Metso SMD, FLSmidth® VXPmill, OUTOTEC HIGmill®, HOSOKAWA ALPINE agitated media mills, NETZSCH mills, Buhler bead mills, DYNO® mills, CMC Supermill PLUS®, 'Red Head' vertical media grinding mills, Niemann Kreis-Basket-Mill®  Getzmann bead mill & basket mill, Vollrath bead mill, HCP Immersion mill, IEC basket mill & bead mills, just name of a few..

 Features

  • High density media ideal for high energy mills, maximizing throughput and productivity

  • High fracture toughness and high wear resistance minimize the contamination of beads during high speed milling

  • At least 15% superior to Ceria Stabilized Zirconia medias in wear rate, proved by many tests

Main Applications

YTZP yttria zirconia beads can be used in milling and dispersion of following materials, just name a few:

  • Bio-tech (DNA, RNA & protein extraction and isolation)

  • Chemicals including Agrochemicals e.g. fungicides, insecticides and herbicides

  • Coating, paints, printing and inkjet inks 

  • Cosmetics (Lipsticks , Skin & sun protection creams)

  • Electronic materials and components e.g. CMP slurry, ceramic capacitors,  lithium iron phosphate battery

  • Food

  • Minerals e.g. TiO2, Calcium Carbonate and Zircon

  • Pharmaceuticals

  • Pigments and dyes

Some other applications, just name a few:

  • Flow distribution in process technology

  • Vibro-grinding and polishing of jewelrys, gemstones & aluminum wheels

  • Sintering bed with good thermal conductivity, can sustain high temperatures
