YSZ Grinding Media
What is YSZ Grinding Media?
YSZ Grinding Media is made of Yttria
Stabilized Zirconia Polycrystal.
Zirconia, in its unstabilized form has
monoclinic, square or cubic crystal
phases. On partial stabilization by Yttria
(Yttrium Oxide), the resultant phase is
tetragonal endowing it with very high
hardness & wear resistance along with high
chemical inertness, making it the best
material for grinding media applications.
After consistent efforts, the research
team at Uniceram Advanced Materials has
developed the grinding media that meets
all the demands of the grinding and
dispersion processes of the industries.

Typical Applications of YSZ Media:
• Paint Industry: For the high purity
grinding of paints and creation of paint
• Electronic Industry: Magnetic materials,
piezoelectric materials, dielectric
materials for high purity grinding where
the media should not discolor the mix
being ground or cause any impurity due to
wearing of the media
• Food and Cosmetic Industry: It is
used in food and cosmetic industry due to
its lack of contamination to in the
materials being ground
• Pharmaceutical Industry: For high purity
grinding and mixing in the Pharmaceutical
industry due to its extremely low wear

Advantages of Using YSZ Grinding Media:
Grinding Media has a density >6.0 gm/cm3
which is 2.5 times that of glass & 1.5
times that of Zircon & Alumina. Due to
this high density, it may be used to mill
even high viscosity compounds, into which
other media may float.
• Gains in Productivity: YSZ Grinding
Media mills 6 times faster than Glass
Media & 3 time faster than Zircon Media.
Thus higher productivity may be achieved.
• Very High Wear Resistance: There is no
contamination by the YSZ Grinding Media in
the material being ground, thus ensuring
the quality of the material being ground.
• Longer Service Life: YSZ Grinding Media
has 25 times longer service life as
compared to Glass Media, 15 times longer
service life than MSZ Media & 5 times
longer service life than Zircon Media.
