系统研究了金属和非金属氧化物及其混合物的低温远红外辐射性能。结果表明,氧化铝、氧化钛、氧化锆、氧化硅、莫来石、高岭土和绢云母等或其混合物是性能良好的低温远红外辐射物质,煅烧对其低温远红外发射率影响不大,而且这些物质在50℃下的4～14μm波段的远红外发射率往往高于其在高温下的同波段远红外发射率。而过渡金属氧化物和其混合物的低温远红外发射性能较其高温远红外发射性能略差,煅烧可显著提高其低温远红外发射性能。
The low-temperature far-infrared radiation performance of metallic and non-metallic oxides and their mixtures was systematically investigated. The results show that alumina, titania, zirconia, silica, mullite, kaolin and sericite, etc., or their mixtures are good low temperature and far infrared radiation materials. Calcination has little effect on the low temperature far infrared emissivity, The far-infrared emissivity of these materials in the 4-14 μm band at 50 ° C is often higher than their far-infrared emissivity at high temperatures. However, the low-temperature far-infrared emission performance of transition metal oxides and their mixtures is slightly worse than that of their high-temperature far-infrared emission properties, and calcination can significantly improve their low-temperature far-infrared emission performance.
