Product Description

High Bonding Strength Ceramic Metallized Rings for Medical Linear Accelerators

Specification of ceramic metallized rings

1. They are made of 95% alumina, 99% alumina, zirconia or beryllia.

2. The max.diameter of ceramic metallized rings can be 50mm

3. We can provide a selection of joining type of metallization, including Mo / Mn and W.

4. Precision processing can be carried out with internal, external and end surface,

5. The best flatness can be 0.01mm, the best tolerance can reach 0.01mm

6. The glazing treatment which enhances the insulation can be done.

Description of metallized ceramic rings

We offer thin or thick deposition metallization on aluminum oxides, zirconium oxide, beryllia or nitride aluminum ceramic body.

With our house-made paints and advanced metalizing equipment, we could deal with a variety of metallized ceramics, including metallized ceramic tubes, metallized ceramic rings, metallized ceramic substrates and so on.

Also, we offer a selection of precision processes, like fine grinding, CNC machining, laser cutting. It helps us to make the dimensions with tight tolerance, also help us to have sufficient capability on cost control.

Typical application of metalized ceramic components
Medical Accelerators Metallized Ceramic Insulator , Alumina Ceramic Liner Ring 1
Metallized ceramic insulators are widely used in electronics, high-vacuum technology, sensors, and medical fields, like vacuum interrupters, electron tubes, feedthroughs, medical linear accelerators/ power tubes, photomultipliers, X-ray tubes, and pressure sensors.
 

Packaging proposal and transportation

1. Vacuum packaging to be a vacuum state with drier as the inner package; 
2. An exported carton as the outer package;  Inside of carton will be filled with protective kinds of stuff.
3. The wooden case will be used if needed when the carton is very heavy.
