Metallized Ceramic Ring
Metallized ceramic rings are usually made from Technical Ceramics, mainly 95% or 99% alumina. Due to the excellent electrical insulation strength, mechanical strength and good thermal properties of alumina ceramics, metallized ceramic rings are often used as Ceramic Insulators / Ceramic Washers in ceramic-to-metal joining applications in high voltage and high current fields.
The most widely used Ceramic metallization method is the sintering of a molybdenum/manganese (Mo-Mn) metal layer followed by nickel plating. We can provide other metal coatings to meet different customer requirements, such as direct silver (Ag) plating on the ceramic body, and tungsten (W) metallization followed by gold (Au) plating.
With our advanced manufacturing equipment, we are able to produce metallized ceramic rings in small to large sizes. We have very high precision processing capabilities in surface grinding, cylindrical grinding and glass grinding, and can meet our customers' strict dimensional requirements.

Why metallization is needed on ceramic surfaces
Combining ceramic materials with metal materials can complement each other in terms of performance. However, the biggest difficulty in the sealing process of the two is that the thermal expansion coefficients of ceramics and metals are quite different, and the wetting effect of metal on the ceramic surface is relatively poor. The two cannot achieve high-quality direct connection, so it is first necessary to sinter or deposit a metal film on the ceramic. This process is the metallization of the ceramic.
How metallization of ceramic surfaces is achieved
The metallization method we use most is the Mo-Mn formula, which is to apply a paste mixture of pure metal powder (Mo, Mn) and metal oxides to the ceramic surface, and then heat it at high temperature in a furnace to form a metal layer. Usually, for ceramic materials after metallization, most processes will perform a secondary metallization treatment on the metallization layer, that is, Ni plating treatment. Ni plating is to improve the fluidity of the subsequent solder on the metallization layer and prevent the solder from corroding the metallization layer. It can also cover the porous Mo layer during the first metallization process to prevent the metallization layer from being damaged after the sealing is completed.
How is the quality of your products
We mainly ensure the quality of the metallized ceramic ring from two aspects: First, production process control. We conduct full product inspection at every link to prevent inferior products from being circulated to the next process. The second is finished product appearance inspection. We ensure the appearance quality and integrity of metallized ceramic rings by using methods such as visual inspection, microscopic inspection, optical measurement and surface roughness testing to ensure that the product meets customer needs and expectations.
