Vacuum Ceramic Component
Our facility has specialized in making vacuum Ceramic Components since 2008; with our comprehensive manufacturing equipment and advanced technologies, the services we offer include the following:
1. Types of ceramic components: tubes and cylinders, rings, rods, and various customized configurations per client’s specifications.
2. Selection of raw materials: mainly including aluminum oxide (Al2O3), zirconium oxide (ZrO2), and aluminum nitride (AlN)
3. From small-size to large-size part: The max. outer diameter up to 200mm, the min. outer diameter is small to 2mm.
4. Tight tolerance: all Ceramic parts can be precisely machined in-house to reach an ideal fitting relationship with synergetic components.
5. Optional Ceramic Metallization: typical molybdenum - manganese (Mo/Mn), Tungsten (W) by silk screen or vacuum sputtering
6. Optional metallic coating on metallization: typical nickel (Ni), direct silver (Ag), gold (Au), Tin (Sn), and direct bonded copper (Cu). You’ll find the typical specifications as follows:
| Standard Dimensional Tolerances | Standard Metallizing System | ||
| As-fired | ± 1%, or ±0.12 mm (±0.005”) | Molybdenum Maganese Thickness (Thick Flim) | 15um ~ 40um |
| Typical ground | Surface : ±0.025 ~ 0.05mm ( ±0.001~0.002”) | Nickle Plating | 3um ~ 6um |
| OD: ±0.025~0.05mm(±0.001~0.002”) | Insulation Strength | ≧ 18KV( D.C ) | |
| ID:±0.05~0.075mm(±0.002~0.003”) | Tensile Strength with Kovar Components | Average 150N/mm2 | |
| Steps, slots: ±0.12mm(±0.005”) | Helium Leak Rate | 10-9 cc/sec | |
7. Offer technical consultation service and Provide ODM service for prototyping cases.
Vacuum ceramic components have the characteristics of high vacuum airtightness, high dielectric strength, low dielectric loss, low dielectric constant, high mechanical strength, high thermal conductivity, good thermal stability, and chemical stability. They are widely used in vacuum electronic devices as tube shells, energy transmission windows, brackets, insulators, etc. If you want to find us a reliable supplier of vacuum ceramic components, be sure to get in touch with us immediately.

Metallized Ceramics for Vacuum Feedthroughs
- StructureVacuum feedthrough usually consists of two parts: the conductive part and the insulating part. The conductive part is made of metal materials, and the insulating part is made of advanced ceramic materials.
Ceramics cannot be directly welded to metal parts. The ceramic surface needs to be metallized first, and then the metallized ceramic is brazed to the metal parts. We generally use ceramic-to-metal sealing technology to braze metal parts into high-purity alumina ceramic insulators. - Product AdvantagesVacuum feedthrough has the following advantages:
1. High insulation: Alumina ceramic, one of its main components, has high insulation and can effectively prevent current short circuit and discharge.
2. High voltage resistance: It can withstand high voltage and ensure the safe operation of electronic devices.
3. High stability: The physical and chemical properties are stable and not easily affected by the environment, thus ensuring the stable performance of electronic devices.
4. High reliability: It is not easy to fail in long-term use. - Application FieldsVacuum feedthrough is mainly used in various vacuum electronic devices, such as vacuum tubes, electron beam devices, electron microscopes, etc.
