Silver powder from the specialist

---

 

Silver powder at the highest purity and different properties is used in many applications: In production of silver-contained contact materials, carbon brushes, diamond tools, on the growth markets of the wind and solar industry, in the field of alternative drives and e-mobility, as a basis for, e.g., ECG- / EEG electrodes in the medical technology and in innovative applications such as antibacterial coatings. Silver powder is also used for conductive polymers, elastomers and preparations such as pastes, varnishes and glues in electrical engineering and electronics.

DODUCO closely cooperates with the customers to develop special silver powder for demanding applications and has a broad range of different production procedures in order to meet these requirements.   

 

Special powder, H-fine	Crystal < 100µ	V 50-100µ

 

 

Various methods are used to produce silver powder

* Spraying liquid silver in water 

  This produces a silver powder with a high tap density, mostly made up of spherical silver particles.

 

* Silver powder-electrolyse

  This produces dentritic to crystalline grain shapes.

 

* Chemical precipitation of silver powder

  This method covers a large bandwidth of desired properties, such as very fine silver particles with large specific surfaces.
