Memory Tip
记忆联想：graphite 像 graph（图）+ ite，石墨是铅笔芯，能写字画图。
Context & Register
语域：mixed 常见场景：materials science、nuclear engineering、pencil production 石墨是标准的技术类用词，正式度通常为中性；多用于材料科学、化学或核工程等专业语境，日常口语说铅笔芯时更常说 lead。
Pronunciation & Spelling
与 graphite 押韵（末尾 /aɪt/）的词：kite、white、fight、right。其中 kite、white 和 graphite 一样拼作 -ite；fight、right 拼作 -ight，但读音相同。注意形近词 graph（/ɡræf/）和 granite（/ˈɡrænɪt/，末尾读 /ɪt/）与 graphite 读音不同。
