How to Write 铪 (hā) — Meaning “Hafnium (chemical element)”

Think of 铪 as 'metal' (钍) that 'fits together' (合) to form hafnium, which is often used in nuclear reactors. The component 合 also resembles two pieces fitting, reminding you that hafnium is a rare metal that combines with other elements.

Pay attention to the left radical 钍: its last stroke is a horizontal line that turns upward, not a separate hook. The right part 合 has a balanced structure with a short top stroke and a wide lower mouth (口). Common mistakes include making the metal radical too tall or misplacing the dot inside 合.

铪 (hā) is hafnium, while 钙 (gài) is calcium and 钚 (bù) is plutonium. Visually, the right sides differ: 铪 uses 合, 钙 uses 丐, and 钚 uses 不. Each represents a distinct chemical element with unique properties and uses.

铪 is almost exclusively used in scientific and industrial contexts, such as in '氧化铪' (hafnium oxide) for electronics or '金属铪' for alloys. It is not a common character in daily life and is mainly encountered by chemistry students or professionals.

Common words containing 铪 include: 铪元素 (hā yuán sù) — The element Hafnium; 金属铪 (jīn shǔ hā) — Hafnium metal; 氧化铪 (yǎng huà hā) — Hafnium oxide.
