Platinum, with its beautiful white luster, is the purest of all the precious metals used for fine jewelry. This grayish white to silver gray metal is harder than gold and very durable with a hardness of 4-4.5 on the Mohs hardness scale, equivalent to the hardness of iron.
Pure tantalum (Ta), with a purity level upwards of 99.9%, is a rare, blue-gray and lustrous metal. Its atomic number is 73. It is highly corrosion resistant, ductile and it conducts electricity and heat very well.

Is there a 100% pure metal
The main way to get a small “100% pure” sample of an element is through simple mass spectroscopy or something similar, where each atom (or even) ion acts individually. This gives you a sample of pure rubidium with a few tens of atoms.
Which metal is pure in nature
Only gold, rare metals and copper are mined on the platinum group in large quantities. On all geologic time scales, very few metals can withstand natural weathering processes such as corrosion, leaving predominantly less reactive materials such as gold and platinum as native metals.
Which is the purest element
Due to their respective reactivity, no substance exists in its pure form. They usually occur in ores as their sulfates or oxides, possibly some with impurities. But the noble gases are in a free state because of their inertness.

Is platinum the purest metal
Typically the purest of all the hard-earned metals used in manufacturing, including high-end jewelry, platinum is known to have an alloy purity of 95%. Platinum has a very bright, whiter luster, especially when alloyed with ruthenium.
Which metals are commercially pure
Some of the precious metals listed below are available in commercial purity, and many can be obtained in extremely pure form, usually 99, at least 999%, which is called “five nine minutes”. For example, 1100 aluminum is actually considered lightweight commercial grade aluminum—it is at least 99% pure. High purity aluminum can be produced up to 99.999% pure.
What are the most precious metals in the world
There are other useful substances that are more valuable or even more popular than gold, which you must build in order to get to know them better. So, here is a unique list of the top 10 precious metals in the world. A good gold detector or XRF can help you locate these precious metals as well. 1. Rhodium
What is high purity metal
High purity metal chemicals are of higher quality than other metal materials and have a wide range of different useful properties. For example, some are magnetic while others are thermoelectric, phosphorescent, and/or semiconductor.
