- A. Imitation rhodium is typically an alloy of copper, tin and zinc, and/or nickel used for plating other jewelry metals like brass and steel to give these metals a bright white, lustrous finish.Plated items include finished pieces, plating on Swarovski crystal, base-metal components and findings.hodium plating can wear off with time. Re-plating rhodium over precious metal findings and jewelry can be done by a jeweler. Imitation nickel-plated findings are another alternative for non-precious metal silver-colored components.

- Ra-226 was used in numerous medical applications during the 20 th Century as well. It was used in sealed and unsealed sources for cancer therapy applications. Ra-226 was fashioned into various sizes and types of sealed sources, many of which were called “needles” because of their shape. Radium needles and other forms were implanted into cancerous tumors to arrest the cancerous growth. In unsealed form, Ra-226 has been used as a source of radon-222 for inhalation therapy.

Investing in Rhodium, the World's Most Expensive Metal As much as 80%-90% of annual rhodium supplies go into the production of automotive catalytic converters, which convert harmful gases from auto exhaust into less harmful substances. Rhodium is exceedingly rare. And there are no pure rhodium mines in existence; rhodium is produced entirely as a byproduct of platinum and/or nickel mining.

The Halides The primary use of fluorite is in the making of steel and aluminum. It serves as a flux making the molten metal flow more easily. Fluorite is a popular specimen mineral for collectors. It comes in nearly every color of the rainbow, sometimes several colors in the same piece creating a striking appearance.

Ruthenium Ruthenium is a chemical element with symbol Ru and atomic number 44. It is a rare transition metal belonging to the platinum group of the periodic table.Like the other metals of the platinum group, ruthenium is inert to most other chemicals.The Baltic German scientist Karl Ernst Claus discovered the element in 1844, and named it after Ruthenia, the Latin word for Rus' .uthenium usually occurs as a minor component of platinum ores; annual production is about 20 tonnes. Most ruthenium produced is used for wear-resistant electrical contacts and the production of thick-film resistors. A minor application of ruthenium is its use in some platinum alloys, and as a catalyst.

- Arsenic has many applications: Some compounds of arsenic are used as insecticides.In medicine, arsenic trioxide is used in the treatment of psoriasis. An isotope of arsenic (A … s-74) is used as a tracer in some diagnostic imaging.Most metallic arsenic is used in forming alloys of lead and copper. (Unalloyed lead is too soft for many purposes).Arsenic atoms are used to create n-type regions in silicon, when fabricating transistors and integrated circuits.

- Uses: As a minor ore of manganese, an ornamental and semi-precious gemstone and as mineral specimens. Rhodochrosite (whose name means rose-colored) is a very attractive mineral with an absolutely one-of-a-kind, beautiful color. Although it can be an ore of manganese, it is its ornamental and display specimen qualities that make it a very popular mineral.

Arsenic The main use of metallic arsenic is for strengthening alloys of copper and especially lead (for example, in car batteries). Arsenic is a common n-type dopant in semiconductor electronic devices, and the optoelectronic compound gallium arsenide is the most common semiconductor in use after doped silicon.rsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining, however. A few species of bacteria are able to use arsenic compounds as respiratory metabolites.

- Radium is highly radioactive. It emits alpha, beta and gamma radiation. If it is inhaled or swallowed, radium is particularly dangerous. Once inside the body, it emits radiation directly to living tissue, where it damages cells.adium is one type of radioactive material that could be found in antiques. When radium was discovered in the early 1900s, people were fascinated by its mysterious glow and it was added it to many everyday products. Adding radium to paint makes it glow-in-the-dark. This paint was used in clock and watch faces and hands.

- Easily magnetized dysprosium compounds can be used in data storage applications such as hard drives, and dysprosium is often used to substitute for some of the neodymium in neodymium-iron-boron magnets. Substituting these high-powered magnets with dysprosium increases their corrosion resistance and coercivity.

Platinum group Rhodium is a noble metal, resistant to corrosion, found in platinum-or nickel ores together with the other members of the platinum group metals.he industrial extraction of rhodium is complex, as the metal occurs in ores mixed with other metals such as palladium, silver, platinum, and gold. It is found in platinum ores and extracted as a white inert metal which is very difficult to fuse.

Rhodium White gold is often plated with a thin rhodium layer to improve its appearance while sterling silver is often rhodium-plated for tarnish resistance. Rhodium detectors are used in nuclear reactors to measure the neutron flux level.t has only one naturally occurring isotope, 103 Rh. Naturally occurring rhodium is usually found as the free metal, alloyed with similar metals, and rarely as a chemical compound in minerals such as bowieite and rhodplumsite. It is one of the rarest and most valuable precious metals.
