Electrolytic Chromium Powder and Granules

Powders and granules are mechanically ground from electrolytic refined chromium material of the appropriate purity, subsequently sieved into the required particle size.

Electrolytic refined chromium powders are used for production of targets.

Electrolytic refined chromium granules are used as evaporated sources for applying chromium coatings in vacuum.
