Element Samples Marketplace

As a part of normal operations over the years Metallium has accumulated many interesting element samples and other related items that are either unique, or not consistently available enough to offer as regular products. This page will grow for a while as new items are added and products will rotate through as they are sold and new items added.

Check back on this page occasionally to view any new and unusual items that are posted.





Silicon Boule Top: This is the tip of a large pure silicon bould that has been cut off as part of the silicon wafer manufacturing process. This particular piece is an unusually attractive specimen as its sharp tip is still intact - most boule tops like this are partially broken. Weighs 4.4 pounds (2 kg) and is highly pure silicon. A beautiful large display piece for the collector. Diameter is 6 inches and height is 7 inches. Can only ship within USA due to weight.

Price: $300.00
Availability: 1 In Stock (Unique)

Osmium Cube: Pure cast Osmium metal in cube format, very rare and difficult to make in this shape. Dimensions are 1cm all around. The market value of the metal in the cube alone is $300 - but the collectibe value is much higher considering the difficulty in fabricating pure Osmium metal into a cube. Actual weight is 22.8 grams. There are a few chips around the edges, as shown in the photos.

Price: $600.00
Availability: 3 in Stock

A spectacular ingot of pure Tellurium showing crystalline surfaces all over. Made with a special process to create the loop shape. Weighs 40 grams, diameter 2.4 inches, 0.14 inches thick.

Price: $60.00
Availability: 1 In Stock (Unique)

Big cylinder of Magnesium metal, polished up nicely. 1.27 inch diameter, 3 inches long, 108 grams.


Price: $60.00
Availability: 1 in Stock

Very high purity Silicon wafer sliced from a large boule for the semiconductor industry. Mirror shine on one side, grainy surface on the other. Perfect shape except for a small chip on the edge. Very thin and delicate. Weighs 54 grams, 7.8 inch diameter, 0.03 inches thick.

Price: $50.00
Availability: Several in Stock

Hemisphere-shaped solid cast ingot of pure Holmium metal, weights 160 grams.. About 2 inches diameter.
