How to Write 磺 (huáng) — Meaning “sulfur (chemical prefix)”

Think of 'yellow stone' because 黄 means yellow and 石 means stone. Sulfur is a yellow mineral, so this character looks like a yellow stone. You can imagine a bright yellow rock labeled 'sulfur'.

The left radical 石 should be written narrower than the right part 黄. When writing 黄, pay attention to the middle part: it contains a 由 (you) shape but with an extra horizontal stroke at the top. A common mistake is to make the left side too wide or to confuse the strokes in 黄.

All three share the 石 radical, but their right parts differ. 磺 has 黄 on the right, meaning sulfur; 碟 has 枼 on the right, meaning a plate or dish; 碡 has 畐 on the right, referring to an ancient stone roller. Visually, 磺's right part is distinct with its 黄 shape, while 碟 looks more like a leaf and 碡 has a square top.

磺 is used as a chemical prefix for sulfur-related compounds, such as 硫磺 (liú huáng, sulfur) and 磺胺 (huáng àn, sulfa drugs). It appears in medical and industrial contexts, rarely in everyday conversation. Sulfur has historical uses in Chinese traditional medicine for skin conditions, so you might see it in pharmacy labels.

Common words containing 磺 include: 硫磺 (liú huáng) — sulfur; 磺胺 (huáng àn) — sulfonamide; sulfa drug; 磺酒 (huáng jiǔ) — sulfa tincture.
