U+9223 "鈣" CJK Unified Ideograph-# Unicode Character

U+9223 "鈣" CJK Unified Ideograph-# is a Chinese character composed of the metal radical (金) on the left and the phonetic component 丐 on the right, primarily used in traditional Chinese and Japanese (as a Kanji) to denote the chemical element calcium. In modern usage, it is most commonly encountered in scientific and medical contexts, such as in the word for calcium (鈣質) in traditional Chinese, and rarely appears in everyday literary or colloquial language. Its simplified Chinese counterpart, "钙," is more prevalent in mainland China, while "鈣" remains standard in Taiwan, Hong Kong, and older Japanese texts. The character’s structure reflects its etymology, where the metal radical indicates its classification as a metallic element, and the phonetic component provides a clue to its pronunciation, which is approximately "gài" in Mandarin and "kai" in Japanese.
