Yttrium Stabilized Zirconia Beads

ZY Photo 1

Now available from Quackenbush! . . . ZY yttrium stabilized zirconia beads.  Very high density (6.0 g/cc) ceramic beads for very high viscosity formulations and applications where exceptionally long bead life and minimal product contamination are desired.  There are other yttrium stabilized zirconia beads available on the market, but none are as cost effective as ZY beads.  Note the highly polished, smooth surface in the photo above.  This characteristic plus the hardness of the beads help to produce very low mill wear and bead wear.  Like any high-density grinding media, your formulation should be optimized for a high density bead.  Using ZY (or any other very high density media, for that matter) with a low viscosity formulation will result in very rapid wear to both the beads and the mill.  Ideally, you should formulate your product to take advantage of the properties of the media.  You may want to visit our free publications "Free Guide to Selecting Mill Medias" and "Free Guide To Milling and Grinding Media Troubleshooting" for assistance in determining if ZY beads are a good choice for your application. 

ZY beads cost approximately 1/3 less than other yttrium stabilized zirconia beads!  Further, ZY beads have approximately half the wear rate of the most popular cerium stabilized beads!  This makes them a very cost efficient alternative, and a "best buy"!

ZY beads are ideal for grinding many products including paints, inks, iron oxides (especially for magnetic tape compounds), cosmetic industry products, and pharmaceuticals.  ZY beads produce very little wear by-products due to their extreme hardness, thus maintaining the integrity of your product.
