Silver powder
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, 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 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.
Applications of silver powder:
- Manufacture of silver-based contact materilas
- Base material for ECG and EEG electrodes and antibacterial coatings in medical devices
- Carbon brushes for electric motors and generators
- Electromagnetic shielding, e.g. conductive sealants and adhesives
- As a conductive pigment in polymer systems in the electronics and electrical industries, e.g. in conductive paints, adhesives and pastes
- Diamond tools
Spraying liquid silver
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
This method covers a large bandwidth of desired properties, such as very fine silver particles with large specific surfaces.
