2022: ☢️ Density of Tantalum (Ta) [& g/cm3, kg/m3, Uses, Sources ...

Everything has mass and volume, and therefore density. So it is expected that the smallest piece of matter, like an atom of Tantalum has it too. But what is the density of an atom of Ta?

Note: Learn more about the density here.

In the case of Tantalum , density is 16.6 g/cm³. However, there are interesting facts about Tantalum that most don't know about. Also check the kg/m³ conversion...

Tantalum Data

Tantalum Density g/cm³

16.6 g/cm³


16600 kg/m³

State at 20 °C



Often used as an economical substitute for platinum. Tantalum pentoxide is used in capacitors and in camera lenses to increase refracting power. It and its alloys are corrosion and wear resistant so it is used to make surgical and dental tools.

When you need to include a fact or piece of information in an assignment or essay you should also include where and how you found that piece of information.

That gives credibility to your paper and it is sometimes required in higher education.

To make your life (and citation) easier just copy & paste the information below into your assignment or essay:

Luz, Gelson. "Density of Tantalum (Ta) [& g/cm3, kg/m3, Uses, Sources ..." Materials. Gelsonluz.com. dd mmmm. yyyy. <URL>

Now replace dd, mmmm and yyyy with the day, month, and year you browsed this page. Also replace URL for the actual url of this page (The < and > stay, ok?). This citation format is based on MLA.
