Sentences with phrase «poor electrical conductor»

Pure water with no exogenous ions in it is a very poor electrical conductor (and even, in fact, functions as an insulator), but because water is such an excellent solvent, it always has impurities in it and these impurities, even in «deionized» water in laboratories, are what creates the electrical conductivity.

Sulfur is a poor electrical conductor and can become unstable over just several charge - and - recharge cycles.

In practice, however, these elements are not suitable electrode materials, as oxygen - based cathodes are inefficient, and sulfur and selenium electrodes are poor electrical conductors.

Less than two years ago, Kanatzidis and his team, with postdoctoral fellow Lidong Zhao as protagonist, identified tin selenide as a surprisingly good thermoelectric material; it is a poor conductor of heat (much like wood)-- a desirable property for a thermoelectric — while maintaining good electrical conductivity.

Wate is a very poor conductor of heat which is why electrical immersion heaters remain hot at the top and not mixed to a uniform temperature.
