| 摘 要： | 以竹炭和电气石为原料,采用机械共混及高温烧成制备了竹炭/电气石复合远红外材料,采用红外辐射测量仪、X射线衍射仪(XRD)、扫描电子显微镜(SEM)及能谱分析仪(EDS)研究了烧成温度对复合材料的远红外比辐射率、物相组成、微观形貌及微区元素组成的影响,初步分析了二者复合对远红外性能的影响。研究表明,随着温度的升高,竹炭/电气石复合材料的远红外比辐射率呈降低趋势,当煅烧温度为700℃时,其比辐射率值达到最大,为0.896。随着温度的增加,复合材料的主要物相发生了明显变化,由组成复杂的NaFe3Al6(BO3)3Si...、NaFe3+3Al6BO3...、CaFe3(Al,Mg)(6BO...和Na0.8Mg3Al6B3O...转化为CaAl2Si2O8、(Ca,Na)(Si,Al)4O8、NaSi3AlO8等。

| Abstract: | A kind of far-infrared composite was prepared with bamboo charcoal and tourmaline by mechanical mixing method and high-temperature firing. The effects of temperature on far-infrared emissivity value, phase composition and microstructure were investigated by XRD, SEM and EDS. Results show that with the increasing of temperature, the far-infrared emissivity value of the composites decreases, which reaches 0. 896 that is the biggest when the firing temperature is 700℃. The phases of composites change from schorl （NaFe3Al6 （BO3）3Si...）, burgerite （NaFe3＋3Al6BO3...）, feruvite （CaFe3 （Al,Mg）6 （BO...）, dravite （Na0.8Mg3Al6B3O...） to anorthite （CaAl2Si2O8）, anorthite- sodian {（Ca, Na）（Si,Al）4O8}, albite {NaSi3AlO8} and so on, when the temperature increases from room temperature to 900℃. |
