Metallized Ceramics Category
We manufacture a variety of refractory metalized ceramics, mainly including metallized ceramic insulator, metallized ceramic tube, metallized ceramic ring, metallized ceramic substrate, Ceramic metallized cylinders.These metallized ceramics is fit for high vacuum, high voltage and high pressure applications due to their exceptional insulation strength, superb bonding strength and excellent metal to ceramic joining hermeticity.
We offer a selection of metallization types to meet special needs via screen printing, pad printing, brushing, the regular types as below:
- Ceramic body base + Molybdenum (Mo/Mn) metallization……………..●Ceramic body base + Silver(Ag) plating
- Ceramic body base + Tin (Sn) plating………………………………………….●Ceramic body base + Molybdenum (Mo/Mn) + Nickle plating
- Ceramic body base + Tungsten (W) + Gold plating……………………… ●Ceramic substrate + Copper(Cu) plating.
Based on in-house comprehensive manufacturing equipment from shaping to electroplating process, we have prototyping to high volume production capability. It helps us to make the dimensions consistency very well, also, helps us to offer a more competitive cost to our customers. Whatever, a very small trial order for R&D program, or extremely high volume need for cost down, we will find a optimal solution there to meet your needs.
These metallized ceramics are widely used in ceramic to metal, ceramic to ceramic joining technology in electrical, electronics, high vacuum technology, medical technology, sensor technology, the typical application like the ceramic insulator/body in vacuum interrupters, vacuum capacitors/thyristor, gas discharge tube, electron tubes, current feedthrough, X-ray tubes, power switches and so on.
We classify products into 4 types：
1) Metallized Ceramic Insulator
2) Metallized Ceramic Ring
3) Metallized Ceramic Tube
4) Vacuum Ceramic Component
you can find the products you need from our classification.
We supply extensive metallized ceramic insulators, they are commonly made of aluminum oxide, zirconium oxide,aluminium nitride and beryllium oxide. A metallic layer will be deposited on specific surface of ceramic body to achieve ceramic to metal, ceramic to ceramic joining, to meet brazing and hermetically purpose.Currently, we offer a selection of types of metallization as following:
– Ceramic base + Mo/Mn metallization – Ceramic substrate + Copper(Cu) plating
– Ceramic substrate + Sliver (Ag) plating – Ceramic substrate + Tin(Sn) plating
– Ceramic base + Tungsten(W) + Gold(Au) plating – Ceramic base + Molybdenum (Mo/Mn) + Nickel (Ni) plating
We are able to produce a variety of special and customized design metallized ceramic insulator per customers’ technical drawing to meet some special application, including metallized ceramic substrate, metallized ceramic ring, metallized ceramic tube and so on. Also we support prototyping to massive production in basis of in-housing comprehensive manufacturing equipment, whatever it’s a very small batch, or high volume demand, we are capable of dealing with them smoothly.
Metallized ceramic insulator is widely used in vacuum interrupters, vacuum capacitors/Thyristors, gas discharge tube, electron tubes, current feedthroughs, X-ray tubes, power switches and so on.
Metallized ceramic ring is commonly made from high puirty alumina, mainly including 95%, 99% aluminum oxide. As alumina ceramic offer excellent electrical insulation strength, great mechanism strength and good thermal properties, so metallized ceramic rings are always used as a ceramic insulator, ceramic washer at ceramic to metal jointing application in high-voltage, high-current fields.
The most extensive type of metallization is ceramic body with molybdenum/manganese (Mo/Mn) metallization, then a following nickle plating will be covered on it. Other different metallic coating is available to supply to meet different requirements, like direct silver (Ag) plating on ceramic body, tungsten (W) metallization with gold(Au) plating and so on.
With our art-of-the-state manufacturing equipement, we are able to produce some different shapes from small-size to large-size, also we have very high precision flating grinding, cylinderical grinding, glazing capability at house, the reach client’s tight dimensional requirement.
The main difference of metallized ceramic tube than regular ones is the applied metal layer on the appointed area of ceramic body. With the applied metal layer on the surface, it can realize the bonding aim between the ceramic tube to metal, ceramic tube to ceramic tube. The metal film will be attached on ceramic parts tightly under high temperature cure. Then the ceramic tubes could be brazed with kovar, stainless steel parts together directly.
In order to increase the wettability at brazing process, in common case, an additional metal plating will be covered on metallization layer further, mainly including nickle plating, gold plating and so on.
In the recent market, alumina metallized ceramic tube is one of most extensive technical parts. They are features of high bonding strength, excellent electrical insulation and mechanical strength.
Sometimes, high precision dimensions is needed to cater to the fitting purpose. With our in-house machining workshop, we are able to make the dimensional tolerance as expected according to customers’ specification.
In the modern industries, advanced ceramic component is very commonly used in many, many electron vacuum devices, like electron tubes, high voltage feedthru, high current feedthru, vacuum interrupter, vacuum capacitors/Thyristors, X-ray tubes and power switches and so on.
The key point is what a metal coating covers on the surface of ceramic body, or ceramic base to achieve the vacuum hermetical and sealing, such as nickle plating, sliver plating, gold plating, copper plating and Tin plating. The main features for vacuum ceramic component as below:
-Extremely high bond/brazing strengths
-High mechanical strength
-Minimum electric resistance and vacuum tightness
-Excellent insulation
The typical form for vacuum ceramic component is to be as an insulator, ceramic packaging and ceramic body etc
