Preparation method of normal-temperature high-radiance infrared radiation ceramic material
The invention discloses a normal-temperature high-radiance infrared ceramic material prepared through rapid laser self-propagating sintering and a preparation method thereof. The preparation method comprises the steps that CuO, Fe2O3, MnO2 and other transition metal oxides are adopted to be subjected to ball milling according to a certain proportion, drying, compacting and tabletting are conducted after ball milling is conducted, then the obtained product is placed in a copper crucible or on other matrixes, laser spot, power, time and other parameters are adjusted to carry out laser irradiation or sintering to enable the raw material mixture to be subjected to high-temperature solid-phase reaction, and thus the AB2O4 type ferrite material is obtained; secondly, the prepared ferrite is crushed, the crushed ferrite is mixed with cordierite according to a certain proportion, a proper amount of a pore-forming agent and a sintering aid are added, long-time ball milling, drying is carried out, and compacting and tabletting are carried out; and high-temperature sintering is carried out by using laser to finally obtain the high-radiance composite ceramic material. The method has the advantages of short sintering time, low energy consumption and the like, and the obtained composite ceramic material has high normal-temperature infrared radiance and wide application prospects.
本发明公开了一种快速激光自蔓延烧结制备常温高辐射率红外陶瓷材料及其制备方法，采用CuO、Fe2O3、MnO2等过渡族金属氧化物按照一定的配比进行球磨，球磨后烘干压实、压片，然后置于铜坩埚内或其他基体上，调节激光光斑、功率、时间等参数进行激光辐照或烧结使原料混合物发生高温固相反应，得到AB2O4型铁氧体材料。其次，将制备的铁氧体破碎与堇青石按照一定比例进行混合，外加适量的造孔剂及烧结助剂进行长时间球磨，烘干压实、压片。利用激光进行高温烧结，最终获得具有高辐射率的复合陶瓷材料。本发明方法具有烧结时间短、能耗低等优势，所获得的复合陶瓷材料具有高的常温红外辐射率，具有广泛的应用前景。
