2(also solidus curve)Chemistry
A curve in a graph of the temperature and composition of a mixture, below which the substance is entirely solid.
- ‘Although the values for the fluidus curve are identical within experimental error, the saturated lipids have a much higher degree of nonideality of mixing at the solidus curve.’
- ‘The upper curve is the liquidus, the lower one the solidus; above the liquidus olivine is liquid, below the solidus it is solid, and between the two curves olivine and liquid coexist.’
- ‘At temperatures between the solidus and the liquidus, an SORT phase, predominantly composed of octadecanol, coexists with a tetradecanol-enriched liquid phase.’
- ‘Solidification begins when the temperature drops below the liquidus; it is completed when the temperature reaches the solidus.’
- ‘Beyond this, nothing can be said of their direction, except, of course, that they must connect liquidus to solidus.’
3historical A gold coin of the later Roman Empire.
- ‘This mysterious funerary currency was cast in China but is an attempt to replicate a silver coin in circulation in Bactria and Northern India between 100 B.C. and 100 A.D. that was in turn a copy of a Byzantine gold coin, the solidus.’
- ‘He established a gold coinage of 72 solidi to the pound, but the other coinage continued to depreciate.’
- ‘Yet another day in the decline of the Empire - and like the solidus and the denarius, the US dollar gets ‘clipped’ a little more each day.’
