High Performance Machinable Zirconia Ceramic Ring Insulation
Tag key words : Machinable zirconia ceramic ring
Manufactured from the highest purity Zirconia, our zirconia Rotors
provide the NMR spectroscopist with the ultimate alternative for
analysis of solid samples. The need to solvate solid samples is
eliminated. They are available for most of the present solid state
NMR spectrometers.
Our Machinable zirconia ceramic ring are carefully examined for material irregularities by various
methods before and after the precision machining process.
High precision (which becomes a necessity for proper spinning
performance) is maintained in the manufacture of the end caps. Most
Zirconia end caps are fitted with o-rings for better sealing. Some
caps have axial holes for venting.
Mingrui Ceramic utilize super-precision, wear-resistant ceramic
stators of silicon nitride or zirconia. MAS spinner materials must
be chosen carefully based on background signals and temperature
ranges. Machinable zirconia ceramic ring of various materials are available to provide fast spinning with
limited background problems.

- Thermal insulation components
- Wear resistance and Cutting blades
- Ceramic knives
- Grinding media
About Zirconia Ceramics :
Zirconia materials are used in very high wear applications under
very high pressure requiring improved fracture toughness and
stiffness over alumina. Zirconia is noted for its high strength,
toughness, wear and thermal properties. Its high material cost
usually warrants its usage extending longer life and reduce down
time where alumina fails in this applications.
During manufacture, the zirconia powder is combined with oxides
such as Yttria, magnesia or tetragonal and the material is said to
be partially stabilised or even it can be fully stabilised if
required, varying the composition allows different properties to be
enhanced.
Yttria (Y-PSZ) stabilised zirconia are mainly used for excellent
wear resistance up to 400’C temperature while Magnesia (MgO-PSZ)
zirconia are very good at high temperature offering excellent
thermal shock and also wear resistance. Y-TZP Zirconia material has
tetragonal in structure and has the highest flexural strength of
all the zirconia based materials. The fine grain size of Y-TZP
lends itself to be used in cutting tools where a very sharp edge
can be achieved and maintained due to its high wear resistance. The
fine grade size leads to a fully dense with excellent mechanical
strength, corrosion resistance, impact toughness, thermal shock
resistance and very low thermal conductivity.
