Nowadays,it is a great challenge to reduce energy consumption and exhaust emission for human activities,in particular,high temperature industries.Among many efforts made to realize energy savings for high temperature furnaces and kilns,the use of high emissivity materials is considered to be an effective route to increase their thermal efficiency by enhancing heat transfer.Most materials with high refractoriness and superior chemical stability have weak infrared absorption and radiation properties;however,their emissivity in infrared regions(1 —25 μm) could be effectively increased by ion doping.This is attributed to three main mechanisms:1) distortion of the crystal lattice;2) increase of free carrier absorption; 3) formation of impurity energy level.In this paper,the development and advancement of various material systems with high emissivity including non-oxides and oxide based ceramics were reviewed.It is also suggested that the establishment of evaluation models or instruments for energy savings would be beneficial to design and application of high emissivity materials in various high-temperature environment.Furthermore,more efforts should be made on durability of high emissivity materials at high service temperatures and on the standardization of testing methods for emissivity. 相似文献

Novel microwave dielectric ceramics in the Li2MnO3 system with high Q prepared through a conventional solid‐state route had been investigated. All the specimens exhibited single phase ceramics sintered in the temperature range 1140°C–1230°C. The microwave dielectric properties of Li2MnO3 ceramics were strongly correlated with sintering temperature and density. The best microwave dielectric properties of εr = 13.6, Q × f = 97 000 (GHz), and τf = ?5.2 ppm/°C could be obtained as sintered at 1200°C for 4 h. BaCu(B2O5) (BCB) could effectively lower the sintering temperature from 1200°C to 930°C and slightly induced degradation of the microwave dielectric properties. The Li2MnO3 ceramics doped with 2 wt% BaCu(B2O5) had excellent dielectric properties of εr = 11.9, Q × f = 80 600 (GHz), and τf = 0 ppm/°C. With low sintering temperature and good dielectric properties, the BCB added Li2MnO3 ceramics are suitable candidates for LTCC applications in wireless communication system. 相似文献
