Back to previous page  Metallium's Element Page Hi Everyone, Thank you for looking at this profile. Metallium is a small company that offers several varieties of element samples for auction and sale. Ebay listings have been offered since early 2003 and during that time the amount of products and elements offered has steadily grown. New products are continually being developed and offered for sale. Many thanks to all of our customers for your support! About Me My background is in Engineering. My career and education have given me much experience with chemistry, metal fabrication, and manufacturing operations that helps me to operate a business like this in an efficient, customer-oriented manner. With regards to the chemical elements, I have been fascinated by them since I was a teenager. Osmium and Yttrium are examples of elements that I had wanted to see and felt were out of reach for a long time. Not any more! I have amassed a large personal collection of elements and started this business by selling my extras on Ebay. It has grown into a full-time business as you can see by the many offerings here. It is fun for me to handle these exotic materials, and several steady customers show their excitement when they see these elements for the first time. Coin-collecting as another hobby of mine has helped me appreciate the "collector bug" that so many people have, not only for elements but for any type of collectible. Metallium's website lists many of the elements that are offered on eBay, and a few more. Check it out at: http://www.elementsales.com Click here to add us to your Favorite Sellers list!

This process was used either to obtain the appearance of an arc-cast pellet or in some cases because of extremely high melting points (iridium, osmium and others). In a nutshell the arc-casting process works like this: The raw metal material (powder, sponge, etc.) is measured on a gram scale and placed in a copper or graphite mold within the arc-melting chamber. The arc-melting chamber is then sealed and evacuated with a vacuum pump to create a vacuum inside the chamber. The chamber is then back-filled with Argon gas, which is a completely chemically inactive gas. This gas will ensure that the metal piece being melted will not have any air (oxygen and nitrogen) to react with during melting. Electrical current is then passed through a tungsten electrode inside the chamber which is positioned close to the metal being melted. An electric arc will jump the gap between electrode and metal and will flow through the metal, heating it very rapidly until it melts. The copper or graphite mold are cooled by a continuous flow of water or coolant to ensure that the mold itself does not melt during the arcing process. Once the metal is sufficiently melted the current is turned off and the arc-cast piece allowed to cool. After cooling the melting chamber is opened and the piece removed and inspected. One of the amazing aspects of the arc-cast process is that it can melt almost any metal, including Tungsten which has the highest melting point of any metal (at over 6192 degrees F or 3422 degrees C). Several other metals that can be melted by the arc-cast process that have melting points over 4000 degrees F include rhenium, osmium, tantalum, iridium and hafnium. Some of the arc-cast pellets offered here will show voids in the center of the piece. This is the effect of rapid cooling and thermal contraction of the liquid metal upon solidification. Note that for precious metal arc-cast pieces the listed prices are higher than the market price of the raw metal due to the cost of the labor and equipment of casting these pieces. This is analogous to silver bars and gold bullion coins which typically sell for a few cents or dollars above the daily quoted spot market price for these metals due the cost of fabrication. The arc-melting process produces cast pieces of a purity that is equal to, or better than the purity of the original raw material. Our suppliers have assured us that they have validated their arc-melt process on a regular basis to ensure that this is the case. The arc-cast pellets offered here are cast in a spherical mold to create the button shape. The mold can be fabricated to create other cast shapes, such as rectangular bars or flat disks. Here is a 100-gram piece of iridium that was recently made special for a customer. It is over 1 inch in diameter (25mm) and feels incredibly heavy in the hand as well as being a beautiful piece to view: Here is another custom-made piece, a 140-gram Ruthenium bar. It is over 2 inches long and over 1/2 inch in diameter: These are 1-kilogram cast ingots of Gadolinium and Samarium, respectively, cast special for a customer. They are over 4 inches in diameter: A perfect Osmium 10-gram piece even made it into a ring that I proudly wear: Following is a stunning series of rods made of several pure metals. The first is one made of solid gold weighing over 19 troy ounces (over 1 pound!). One half of these rods was polished to a mirror finish with the other half left in an unfinished state. This one is of solid Platinum weighing over 21 troy ounces. At the time of the sale of this piece the market value of the metal in this piece was over $18,000.00. This one is Palladium weighing 12 troy ounces. A larger rod made of pure Tin weighing 1 kilogram: And a 1-kilogram rod of Bismuth: On a different note, here are samples of elements preserved in clear acrylic resin. The first one is Bromine sealed in a glass ampoule within the acrylic and the second is a crystalline disc of Tellurium: Rare-Earth Metal Chunks All of the rare-earths are offered in our listings (except for the radioactive Promethium of course) and come in two general forms: Cut from cast ingots, or distilled (dendritic). Lanthanum, Cerium, Praseodymium and Neodymium are cut from larger ingots that have been cast in a mold. These pieces are completely solid and uniform with no internal voids. Since the melting points of these metals is relatively low (about 1500 degrees F) casting is not difficult. All the other rare earths are in dendritic form. These metals were purified by either distillation or sublimation (yes, from a vapor!) under high vacuum and condensed directly from the vapor. The solid metal is then removed from the condensing chamber and has what is called a dendritic structure. Samarium is probably the best demonstration of this structure. The metal is solid but has a definite "grain" to its structure, forming as long and thin "dendrites" which can be broken off from the main bulk. Sometimes this structure creates a very attractive and shiny crystalline appearance. The metal pieces will have internal voids and may be "stringy" in appearance.
