The Mechanical Preparation (continued)
Oxide Polishing material
Alumina suspension: MasterPrep and MicroPolish
The importance of alumina slurries as the sole
polishing medium has declined over the past years
due to the availability of economical diamond
products and the better results they achieve. Also,
because semi or fully automatic preparation
equipment is more commonplace, there is a need for
continual dosing.
Alumina suspensions are suitable after diamond
grinding or as final polish (0.05μm). An alternative to
pre-dispersed alumina suspension is MicroPolish
alumina powder. The powder is mixed with distilled
water to obtain the required suspension. All alumina
products are equally suitable for the polishing
process of metals, composite materials, minerals and
ceramic materials.
Deagglomerated Alumina: MicroPolish II
During the production process, alumina develops
agglomerated particles. In the ideal case, these
agglomerates are broken during polishing into
single crystals. This does not always happen during
processing of soft materials such as copper,
aluminium or lead, because of the low pressure used
during the preparation. As a result unwanted
scratches often appear on the surface. With the
deagglomerated alumina products, only single
crystals are available and they exhibit excellent
cutting characteristics. With MicroPolish II products,
high surface flatness can be reached in shorter time.
Final polishing suspensions: Final, MasterMet and
MasterMet 2
These are final polishing products made of colloidal
silica where high surface flatness can be obtained
with metals, solder, composites coating layers.
Particularly with tough or soft materials, the
deformation layers are removed by the special
action of these alkaline suspensions. The
suspensions are used after diamond or alumina
steps. These suspensions can also be used in
combination with suitable etching agent for the
chemical-mechanical polishing of difficult samples
e.g. titanium.
MasterPolish and MasterPolish 2
MasterPolish suspensions are mixed oxide products
for fine grinding and final polishing of ceramic
materials, semiconductors, hard metals and
composite materials with non-metallic components.
The polishing effect takes place via a chemomechanical
action, i.e. the polishing agent reacts on
one hand with the surface of the sample and causes
chemical erosion, on the other hand the oxide
particles create mechanical erosion. The results are
unusually high removal rates and a highly-polished,
scratch and relief-free sample surface. MasterPolish
is usually used undiluted and is particularly effective
when using polishing cloths without nap such as
TexMet cloths. For the final polish, it can be used
with our regular oxide polish cloths.
