How to Write 钽 (tǎn) — Meaning “tantalum”

Imagine a metal (钅) container that you open at dawn (旦) to find a rare element inside – tantalum. The picture of opening a metal box at sunrise helps link the components to the meaning.

The left radical 钅 is written with three horizontal strokes and a vertical hook, finishing with a short stroke; make sure the hook is not too long. The right part 旦 has 日 (sun) on top and a horizontal line below – keep the bottom stroke slightly longer than the top of 日 to balance the character.

钽 (tantalum) has the right side 旦 (dawn), while 钍 (thorium) uses 土 (earth) on the right, and 钎 (drill rod) uses 千 (thousand). Visually, 钽 has a horizontal line above and bottom line in 旦, 钍 has a simple earth shape, and 钎 has a cross-like 千. Their meanings are all different metals or tools.

钽 almost always refers to the metal tantalum, used in specialized industrial and electronic contexts, such as 钽电容 (tantalum capacitor) in electronics. It is a rare element with high corrosion resistance, so you might see it in technical manuals or materials science discussions, but not in everyday conversation.

Common words containing 钽 include: 钽电容 (tǎn diàn róng) — tantalum capacitor; 钽金属 (tǎn jīn shǔ) — tantalum metal; 钽丝 (tǎn sī) — tantalum wire.
