How to Write 铼 (lái) — Meaning “Rhenium”

Think of "lái" like "lie" – imagine a lie about a metal that is actually very rare and valuable. Or associate 来 (come) with "rhenium coming" into your memory as a shiny metal.

Write the left radical 钅 first with three horizontal strokes and a vertical hook. Then add the right part 来, which has a horizontal line on top and a vertical line through the center. Keep the character balanced so the left and right sides are similar in height.

铼 has the radical 钅 with 来, while 钰 has 钅 with 玉 (yù, jade) and means a precious metal or jade. 钱 has 钅 with 戋 (jiān) and means money. Their pronunciations and meanings are completely different, so look at the right side to tell them apart.

铼 is used mainly in scientific and industrial contexts, such as 金属铼 (rhenium metal) and 铼合金 (rhenium alloy) for high-temperature parts in jet engines. It is not a common daily character, but appears in chemistry and metallurgy discussions.

Common words containing 铼 include: 金属铼 (jīn shǔ lái) — Rhenium metal; 铼合金 (lái hé jīn) — Rhenium alloy; 铼的用途 (lái de yòng tú) — Uses of rhenium.
