Zirconia Ceramic Wafer for Insulation / Ceramic Circular Plate /
Discs
Key words : Ceramic Wafer / Ceramic Circular Plate
A superb combination of corrosion resistance, temperature stability
and non-conductivity
Outstanding corrosion resistance to acids, solvents, salts, and organics
Excellent electrical & thermal insulator
High purity
Ceramic Wafer / Ceramic Circular Plate are one of the most thermally resistant washers available. Due to
their outstanding thermal resiustance, alumina ceramic washers are
geared for the most demanding high temperature applications.
Alumina ceramic washers also have outstanding corrosion resistance
and are highly chemically resistant to acids, solvents, and salts.
Additionally, alumina ceramic washers find many uses in high
voltage applications due to their non-conductive electrical
properties.
Alumina ceramic washers are available in both metric and standard
sizes. Please contact us if you have any questions about the
properties or availability of our ceramic washers.
washers made from customer specified ceramic grades or custom
dimensions are available upon request.
Common Ceramic Grades
Alumina ceramic or Aluminum oxide (Al203) is the most common grade of alumina ceramics and is designated as
being 95% up pure. Alumina is most known for high temperature
stability and has a usable temperature limit of 3000°F (1650°C).
Alumin has the greatest balance of economy, mechanical and thermal
properties.
Various other compositions of alumina ceramic are available upon
request.
In stock fully dense Alumina Oxide and Zirconia Oxide ceramic
washers / spacer is the most widely used advanced ceramic material.
It offers very good performance in terms of wear resistance,
corrosion resistance and strength at a reasonable price. Its high
dielectric properties are beneficial in electronic products.
Both the Alumina Oxide washers and Ceramic Wafer / Ceramic Circular Plate have matching ceramic screws and ceramic nuts.
If a special shaped or size ceramic washers is required, please
advise and we will be happy to quote in both small quantities and
large quantities.
High-quality Ceramic Wafer / Ceramic Circular Plate (aluminum oxide Al2O3 99.9%, 99.7% and 95% and zirconia ZrO2)
Mingrui manufactures high qualityCeramic Sleeve Washer / Ceramic Sleeve Bushing, made out of High Purity Alumina (95%, 99,7% or 99,9%) and TZP
Zirconia ceramics for high and low pressure injection and selection
valves. Rotors and Stators are subject to intensive mechanical
stress and chemical aggression while having to maintain a perfectly
leak free adjustment between the two components. No leak, limited
stiction and low wear are the most important parameters to
guarantee long life and reliability to your valve. These can be
achieved by an adequate surface finish, a perfect flatness of the
surfaces in contact and a proper selection of the material. Every
application is different and Ceramaret will help you define the
parameters required for your particular valve. Ceramic Wafer / Ceramic Circular Plate are used in valves for many high-tech applications, such as HPLC,
micro-HPLC, Medical, Industrial, etc.
Advantages ofCeramic Sleeve Washer / Ceramic Sleeve Bushing:
1. Isostatic pressed.
2. Fire resistance.
3. Superior mechnical strength.
4. High corrosion and wear resistance.
5. High Temperature Resistance.
6. Good Insulation Performance Precision.
7. Zirconia and alumina ceramic material.
They are high corrosion and wear resistance and strong impact
resistance and delivers 10 times longer working life than metal
plunger. They give a longer life to the sealed packing material.
