Nettet16. des. 2016 · Refractories are those materials which have high melting points and have properties which make them suitable to act as heat resisting barriers between high and low temperature zones. Refractories are inorganic, nonmetallic, porous and heterogeneous materials composed of thermally stable mineral aggregates, a binder phase and additives. Nettet1. jun. 2024 · Therefore, the selection of an appropriate insulating refractory material becomes crucial. This kind of refractory is usually a highly porous material with low thermal conductivity <1 W m −1 K −1. The conductivity may vary with temperature and can evolve with the state of the microstructure [2].
