Fusibility \Fu"si*bil"i*ty\, n. [Cf. F. fusibilit['e].] The quality of being fusible.


n. The ease with which a material will melt.


Fusibility is the quality of objects of being fusible or convertible especially to heat. Materials such as solder require a relatively low melting point so that when heat is applied to a joint, the solder will melt before the materials being soldered together melt, i.e. high fusibility. On the other hand, firebricks used for furnace linings only melt at very high temperatures and so have low fusibility. Materials that only melt at very high temperatures are called refractory materials.

Usage examples of "fusibility".

It is more satisfactory to separate the chloride, which may be recognised by its taste, flame coloration, fusibility, and negative action with reagents.

Fluorides generally are fusible, and impart fusibility to substances with which they form weak compounds.
