High purity 99,999 % Crystals and Grains

Highest quality for highest requirements

In addition to the proven silver powders, DODUCO now also offers silver crystals in highest purity 99.999% Ag.

Grains are also available on request.

This purity is required for sensitive vapour deposition processes, e.g. in the production of semiconductors.

This above-average purity of 5N is also needed to create analytical standards for very sensitive analytical standards.


After regular silver refining, this particularly high-quality 99.999 silver undergoes a series of further purification steps

to further optimise the already high product quality of the LBMA-certified fine silver (99.99% Ag).





Of course, a corresponding analysis is enclosed with every delivery batch.

Please send us your specification so that we can provide you with an individual offer
