Nettet6. feb. 2024 · The thermal conductivity of the alkali-activated slag porous material was determined to be λ = 0.0985 W/m·K, and the thermal conductivity of phosphogypsum increased it by 88.1% (λ = 0.1852 W/m·K) after adding 5% to the material, the addition of 10% increased the thermal conductivity of phosphogypsum by 165.8% (λ = 0.2618 … NettetA light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. When current passes through an LED, the electrons recombine with holes emitting light in the process. LEDs allow the current to flow in the forward direction and blocks the current in the reverse direction.
