The indirectly heated fluidized-bed furnace is heated electrically though a fluidized-bed furnace may also be gas heated. Fluidized beds have been designed to perform a wide variety of heat treating tasks including stress relieving, preheating, hardening, quenching, annealing, and tempering, as well as a variety of surface treatments such as carburizing, nitriding, and steam tempering.

A quasiparticle that can transfer heat under electrical control
Scientists have found the secret behind a property of solid materials known as ferroelectrics, showing that quasiparticles moving in wave-like patterns among vibrating atoms carry enough heat to turn the material into a thermal switch when an electrical field is applied externally. A key finding of the study is that this control of thermal conductivity […]
