Rhenium is a member of the noble metals sub-group, but unlike the other members it doesn't seem to be used in jewelry, though it probably could be. Others in the group are cheaper, prettier, or just more fashionable.

Rhenium Rhenium in Wolframite
Rhenium in Wolframite.
This is basically a fine powder which is said to have been determined by neutron activation analysis to be microscopic inclusions of rhenium in wolframite grains. No reason to doubt the claim. But it is a good bit of money to pay for a powder that, honestly, looks a lot like just about any other powder.
It is described as coming from eastern Transbaikal, Russia (interestingly the tag it came with is marked "E. Transbaikal, U.S.S.R.", indicating that the sample must have been collected some time ago).

Rhenium Old photographic flash bulb
Sound3DOld photographic flash bulb.
Back in the dark ages, cameras used one-time-only flash bulbs that ignited a fine wire inside a glass bulb. We're not concerned here with the fine wire, but rather with the "igniter": these top-quality GE #5 bulbs were advertised as coming with "the guaranteed RHENIUM igniter". I don't know for sure what metal the wire in this one is made of, but I have a different type under zirconium which is labeled as using a wire of that metal (but that one doesn't say what it's igniter is made of).
Reports Tryggvi:
The woolly stuff in GE flashbulbs is zirconium. (I.e. , the stuff that burns and makes the light. The bulbs are also filled with a few atmospheres of oxygen). The flashbulbs in the cubes that were used on some Kodak Instamatics were not triggered electrically (with rhenium wire), but with a percussive pyrotechnic mix inside a little metallic tube that stuck out of the bulb.

Rhenium Sample from the RGB Set
3DSample from the RGB Set.
The Red Green and Blue company in England sells a very nice element collection in several versions. Max Whitby, the director of the company, very kindly donated a complete set to the periodic table table.

To learn more about the set you can visit my page about element collecting for a general description or the company's website which includes many photographs and pricing details. I have two photographs of each sample from the set: One taken by me and one from the company. You can see photographs of all the samples displayed in a periodic table format: my pictures or their pictures. Or you can see both side-by-side with bigger pictures in numerical order.

The picture on the left was taken by me. Here is the company's version (there is some variation between sets, so the pictures sometimes show different variations of the samples):

Rhenium Sample from the Everest Set
Sample from the Everest Set.
Up until the early 1990's a company in Russia sold a periodic table collection with element samples. At some point their American distributor sold off the remaining stock to a man who is now selling them on eBay. The samples (except gases) weigh about 0.25 grams each, and the whole set comes in a very nice wooden box with a printed periodic table in the lid.

To learn more about the set you can visit my page about element collecting for a general description and information about how to buy one, or you can see photographs of all the samples from the set displayed on my website in a periodic table layout or with bigger pictures in numerical order.

Rhenium Before and after arc-melting
3DBefore and after arc-melting.
This shows what happens when you blast some compressed rhenium powder (left) with a high-current electric arc in an arc melting furnace (under an inert argon atmosphere): You get a nice shiny button of solid rhenium (right). Max Whitby made this button while visiting an arc melting furnace at Leeds university: It worked so well now he's working on building one himself, using a welder as the power source.

He'll use it to make solids out of powders for a number of elements that are much cheaper in powder form, for use as samples in his commercial element set.

Rhenium Rhenium foil
3D3DRhenium foil.
These are tiny little strips of rhenium foil about half an inch long. If they were made of aluminum this would be a pile of fluffy shreds. But it's rhenium, one of the hardest and densest elements, so instead it's a surprisingly heavy mass of fairly stiff strips.

Rhenium Museum-grade sample
3D3DMuseum-grade sample.
In early 2004 Max Whitby and I started selling individual element samples identical or similar to the samples we use in the museum displays we build. These are top-quality samples presented in attractive forms appropriate to the particular element. They are for sale from Max's website and also on eBay where you will find an ever-changing selection of samples (click the link to see the current listings).
This bottle contains about 50 grams of arc-melted buttons made in Max's reduced-pressure argon-arc furnace.

Rhenium Sintered button
3DSintered button.
This is a compressed and sintered button of rhenium powder. It could be melted down into a solid button in an arc or e-beam furnace (see above), but it's interesting to keep a few of these around in pre-melted condition for comparison. I got this one from Oliver Sacks on a visit to New York, during which we visited a company in New Jersey to melt his kilogram of iridium down into a solid slab.

Rhenium Machined bar
3D3DMachined bar.
This absolutely stunning precision-machined bar of solid rhenium is worth a pretty serious amount of money, though Max got a great deal on it on eBay. Its density is around 20.5g/cc, slightly less than the theoretical density of 21.0g/cc. It's common for large bars of very high melting point metals like this to be lower in density than they should be, because they are formed by sintering a fine powder of the metal under high pressure (casting such a large piece being virtually impossible). The sintering process leaves microscopic voids, which must be compressed out by hammering, swaging, and the like in an attempt to beat the metal to the highest possible density.

I chose this sample to represent its element in my Photographic Periodic Table Poster. The sample photograph includes text exactly as it appears in the poster, which you are encouraged to buy a copy of.

Rhenium Tungsten-rhenium alloy x-ray tube
3D3DTungsten-rhenium alloy x-ray tube.
The conical disk in this sample is a heavy slab of tungsten-rhenium alloy. The structure above holds a filament that releases electrons, which are accelerated with a high voltage to strike the tungsten-rhenium disk, generating x-rays when they strike.
In operation the disk is spinning, because if it ever stopped the heat generated by the electrons slamming into the metal would start melting it. The small scratch towards the right is the explanation for why I have this tube: It's where the disk stopped and got burned.
Normally this whole setup would be inside a glass vacuum tube, but it broke in shipment, saving me the trouble.

Rhenium Big bag of beads
3D3DBig bag of beads. (External Sample)
This is a large ($18,000) order of platinum group metals placed by an excellent customer of my partner Max Whitby's element sales business. I happened to be visiting Max in London just before the order needed to be shipped to our customer in the US, so I hand-carried the precious cargo home rather than risking international shipping. These beads were made by Max in his reduced pressure argon arc furnace.

The customer wishes to remain anonymous, so you'll just have to keep wondering where this remarkable trove of rare metals currently resides: The only thing you can be sure of is that I don't have it.

Rhenium Photo Card Deck of the Elements
3D3DPhoto Card Deck of the Elements.
In late 2006 I published a photo periodic table and it's been selling well enough to encourage me to make new products. This one is a particularly neat one: A complete card deck of the elements with one big five-inch (12.7cm) square card for every element. If you like this site and all the pictures on it, you'll love this card deck. And of course if you're wondering what pays for all the pictures and the internet bandwidth to let you look at them, the answer is people buying my posters and cards decks. Hint hint.
