noun
Scientific term for the temperature at which a solid becomes liquid. Often used in chemistry and materials science.
氷の溶点は0度です。
The melting point of ice is 0 degrees.
この金属は溶点が高い。
This metal has a high melting point.
融点 is the more common and standard term for 'melting point'. 溶点 is a variant with the same meaning but less frequently used.
Compound of 溶 (you, 'melt') + 点 (ten, 'point'). The kanji 溶 specifically refers to dissolving or melting, while 融 (as in 融点) is more common for the scientific term.
