Etymology

Origin of critical temperature

First recorded in 1865–70

Example Sentences

Zentropy theory can then estimate the critical temperature at which the material loses that property.

From Science Daily

"It is ductile at room temperature, its melting point is as high as about 2,000 degrees Celsius, and -- unlike refractory alloys known to date -- it oxidizes only slowly, even in the critical temperature range. This nurtures the vision of being able to make components suitable for operating temperatures substantially higher than 1,100 degrees Celsius. Thus, the result of our research has the potential to enable a real technological leap," says Kauffmann.

From Science Daily

"By identifying critical temperature thresholds, we get insights into when crop yields may begin to decline, which will guide policymakers in making more beneficial strategies," said Misra.

From Science Daily

Conventional superconductors are not sensitive to non-magnetic disorder, so this test would show no or very little change in the critical temperature.

From Science Daily

Unconventional superconductors have a high sensitivity to disorder, and introducing defects changes or suppresses the critical temperature.
