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.
Advantages of Machinable zirconia ceramic ring
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.| Magnesia ZrO2+MgO | Yttria ZrO2+Y2O3 | Tetragonal ZrO2+ YTZP | Toughened ZrO2+Al2O3 | |
