Unicode Version 18.0
Source: Browser Default
U+77FD "矽" CJK Unified Ideograph-# is a Chinese character that primarily refers to the element silicon, often used in scientific and technical contexts. It is composed of the radical for "stone" (石) on the left, indicating its association with minerals or solid nonmetals, and a phonetic component on the right that contributes to its pronunciation, which is "xī" in Mandarin. While in modern Chinese, "硅" (guī) is more commonly used for silicon, "矽" persists in specialized fields such as chemistry and electronics, and it was historically the standard term before the adoption of "硅" in mainland China. The character also appears in some proper names and older texts, reflecting its role in the development of Chinese scientific vocabulary.
