Processing
Zirconia (ZrO2)
 |
Zirconia
is characterised by its:
 |
unparalleled fracture strength |
|
high wear resistance |
|
high corrosion resistance |
|
low heat conductivity |
|
For all these reasons, zirconia is a preferred material
in high-tech ceramics, on the medical sector (hip joints,
dental restorations and fillings, etc.), in the electronics
industry (fuel cells, vacuum tubes, etc.), as well as
in the field of mechanical and system engineering (nozzles,
valves, pumps, etc.).

The required end-product finenesses
are usually in the submicron range.
These high requirements can be met with our agitator ball
mills AHM. The particle size distribution shown below
for a product with a d50
of 0.5 µm at a d97
of 1.2 µm was achieved with this mill.
Zirconia is generally manufactured to different degrees
of chemical stabilisation and then ground. The grindability
and ease of processing are strongly dependent on the formulation
of these mixtures. The agitator ball mill AHM is capable
of processing suspensions of high viscosity, whereby good
wear protection of the mill components and the use of
extremely small grinding pearls can be realised. |
