Gold
Atomic number: 79
Atomic weight: 196.966569

Great potential in applications
for catalysts to anticancer drugs

Used as a protective film
against infrared radiation

Platinum is widely used, for example,
in auto-exhaust catalysts and active
pharmaceutical ingredients inanticancer drugs. Platinum is one ofthe precious metals with great
potential.

Gold is highly malleable and can beprocessed into thin wires and foils.
Gold has an infrared reflectance of as
high as 98.4% and therefore, gold
thin film is used as protective film forspace shuttles.

Photographs would not have been

Absorbs a large amountof hydrogen

A large amount of silver, as silver
nitrate, is used in photographic
sensitive materials. Silver has thehighest reflectance to visible light
among metals, and is therefore usedin mirrors.

Palladium can absorb 350 to 850
times its own volume of hydrogen (atambient temperature). Palladium has
high permeability and therefore, iseffective for use in high-purity
hydrogen production equipment.

Rhodium does not dissolve in any

Superior hardness andcorrosion resistance

Rhodium is chemically stable anddoes not dissolve in acids or aquaregia.
Rhodium plating is very useful for use
in reflectors for searchlights and as
decorative plating.

Iridium becomes harder when it isalloyed with platinum and palladium,providing increased corrosion
resistance. Iridium is therefore usedin auto spark plugs.

Ruthenium has high expectations asa catalyst for a pollution-freehydrogen energy system that
decomposes water with solar rays,
produces hydrogen, and stores thehydrogen as fuel.

Osmium is most easily oxidized
among platinum-group metals, and is
rapidly oxidized when it is heated inair. Osmium is very useful in detecting
fingerprints and as a stain for fatty
tissues.

Corporate History

History,

TANAKA Precious Metals began its life as a money exchange firm in 1885.
In 1907, we succeeded in processing platinum wire, and since then we have manufactured a wide
range of different industrial products using precious metals.
Throughout the ages, our approach to precious metals has always been one of high aspirations.
