Moderate thermal conductivity
Web8 jan. 2024 · The thermal conductivity of refractory bricks, that is, their ability to transfer heat, is usually expressed in terms of thermal conductivity. Thermal conductivity refers to the amount of heat passed per unit area in unit time and unit temperature gradient in the process of energy transfer. WebThermal conductivity is a measure of a materials ability to pass heat through it. Materials with a high thermal conductivity can effectively transfer heat and readily take up heat from their environment. Poor thermal conductors resist heat flow and obtain heat slowly from their surroundings.
