Precious metal pellets are cylindrical pieces of a precious metal such as platinum, gold, silver, or palladium. Slugs (also known as granules or grenailles) are fine precious metals in the form of small, irregularly shaped balls.
IAM Drijfhout offers pellets and slugs in various types of precious metals such as platinum, gold, palladium, and silver. We work with the purest precious metals to guarantee high quality. Various shapes and sizes are available.
For the pellets, common precious metal purities are:
For the most demanding applications (and to optimally limit specific impurities), there is the option to specially request gold pellets with a purity of Au 99.999%.
Common dimensions of precious metal pellets are:
For slugs/granules, the size of precious metal grains varies from tiny pieces barely visible to the naked eye to larger lumps.
Pellets and slugs of precious metal are used in various industrial applications. They are widely used in evaporation processes (thin film deposition) in the production of wafers for (micro)chips, medical equipment, and other applications where precision and high purity are required.
The application of thin films, or thin layers of precious metal, is widely used by technology industries such as universities, cleanrooms/nanolabs, and research institutes.
The quality of a precious metal, such as its purity and composition, can vary greatly. To ensure that the required properties are present in a thin film process, it is necessary that the source material used is very pure.
Moreover, a precious metal like gold can be sensitive to splashing during evaporation, which can lead to defects in the deposited film. Therefore, it is very important to provide a high and consistent quality of precious metal.
Leftover pellets and slugs can be send to IAM Drijfhout for recyling, enabling the efficient and sustainable reuse of precious metal. For more information, please visit the recycling service page.
