Translation guide
The English word 'sublimation' has two main uses: a scientific meaning (solid turning directly into gas) and a psychological meaning (channeling impulses into socially acceptable activities). This guide covers both, with a focus on natural Japanese expressions for each context.
Describing the physical process where a solid turns directly into a gas without becoming liquid.
The standard scientific term for sublimation. Used in chemistry, physics, and everyday contexts when discussing dry ice or mothballs.
ドライアイスは常温で昇華する。
Dry ice sublimates at room temperature.
昇華は固体が直接気体になる現象です。
Sublimation is the phenomenon where a solid turns directly into a gas.
The verb form, meaning 'to sublimate'. Used in both technical and casual descriptions.
ナフタレンは室温で昇華する。
Naphthalene sublimates at room temperature.
Referring to the Freudian defense mechanism where socially unacceptable impulses are transformed into socially acceptable actions or behaviors.
The standard psychological term, directly borrowed from the physical concept. Used in psychology and everyday language to describe turning negative energy into positive pursuits.
彼は攻撃的な衝動をスポーツに昇華させた。
He sublimated his aggressive impulses into sports.
芸術はしばしば苦しみの昇華から生まれる。
Art often arises from the sublimation of suffering.
The causative form meaning 'to sublimate (something)'. Commonly used when someone consciously redirects their impulses.

In Japanese, 'evaporation' is 蒸発 (じょうはつ). Sublimation (昇華) specifically means solid to gas, while evaporation is liquid to gas. Using 蒸発 for dry ice would be incorrect.
The same word 昇華 is used for both scientific and psychological meanings. In conversation, the topic (chemistry vs. emotions) will clarify which sense is intended.
