FAQ

General Information

Q1: What is a single-sided polished ceramic ring?
A1: A single-sided polished ceramic ring is a ceramic component where one side has been polished to a smooth finish, while the other side remains unpolished. This specific ring is made from 95% alumina (aluminum oxide).

Q2: What are the key properties of 95% alumina ceramic?
A2: 95% alumina ceramic is known for its high hardness, excellent wear resistance, good thermal stability, and high electrical insulation properties. It is also chemically inert and resistant to corrosion.

Applications

Q3: What are the common applications of single-sided polished ceramic rings?
A3: These rings are used in various industries, including electronics, mechanical engineering, and chemical processing. They serve purposes such as insulators in electronic devices, wear-resistant components in machinery, and protective barriers in corrosive environments.

Q4: Why is only one side polished?
A4: Polishing only one side of the ceramic ring reduces production costs and time while providing the necessary smooth surface for specific applications, such as mounting or sealing against other components.

Technical Specifications

Q5: What are the typical dimensions available for these ceramic rings?
A5: Dimensions can vary based on specific requirements, but typical sizes range in inner diameters from a few millimeters to several centimeters. Outer diameters and thicknesses also vary accordingly.

Q6: What is the significance of the 95% alumina composition?
A6: The 95% alumina composition provides a balance between high mechanical strength, thermal stability, and cost-effectiveness. It is suitable for most industrial applications requiring robust and durable ceramic components.

Handling and Maintenance

Q7: How should I handle the single-sided polished ceramic ring?
A7: Handle the ring with care to avoid chipping or breaking, especially along the polished surface. Use appropriate tools and wear gloves to prevent oils and dirt from contaminating the polished side.

Q8: How do I clean the polished ceramic ring?
A8: Clean the polished side with a soft cloth and a mild detergent solution. Avoid abrasive materials that could scratch the surface. For tougher stains, use a specialized ceramic cleaner.

Purchasing and Customization

Q9: Can I order custom-sized ceramic rings?
A9: Yes, many manufacturers offer customization options for size, thickness, and specific tolerances to meet particular application needs.

Q10: What is the typical lead time for an order?
A10: Lead times can vary based on the manufacturer and the quantity ordered. Standard sizes may be available for immediate shipment, while custom orders may take several weeks.

Troubleshooting

Q11: What should I do if the ring arrives damaged?
A11: Inspect the ring upon delivery. If it is damaged, contact the supplier immediately to arrange for a replacement or refund according to their return policy.

Q12: How do I ensure the ring maintains its properties during use?
A12: Ensure the ring is used within its specified operational limits for temperature, pressure, and environmental conditions. Avoid exposure to conditions beyond its designed capabilities.
