Preparation method of double perovskite type In2Te-M-O6 nano material
The invention relates to a nano material preparation technology, and aims to provide a preparation method of a double perovskite type In2Te-M-O6 nano material. Comprising the following steps: preparing a mixed solution containing In < 2 + > and Te < 4 + >; continuously adding a precursor containing a structure modifier M, and stirring to obtain a uniform solution; adding a complexing agent, and continuously reacting to form precursor sol; adding the precursor sol into a reaction kettle for hydrothermal curing reaction, removing supernate after hydrothermal curing reaction is completed, centrifugally washing a solid product, and freeze-drying to finally obtain the nano material. The material prepared by the invention has a high-temperature decomposition characteristic similar to that of a CdO reinforced phase; the nanometer material structure is beneficial to increase of the effective contact area between nanometer materials, and the conductive property higher than that of a SnO2 reinforced phase is achieved, so that the electrical property of the silver-based electrical contact material can be effectively improved. The product is controllable in morphology and size, the electrical and thermal properties of the electric contact material can be effectively improved, the reaction synthesis condition is simple, and the cost is low.
本发明涉及纳米材料制备技术，旨在提供一种双钙钛矿型In2Te‑M‑O6纳米材料的制备方法。包括：制备含有In2+和Te4+的混合溶液；继续加入含有结构修饰剂M的前驱体，搅拌获得均一溶液；加入络合剂，持续反应后形成前驱体溶胶；将前驱体溶胶加入反应釜中进行水热熟化反应，完成后去除上清液，离心洗涤固体产物，经冷冻干燥最终获得所述纳米材料。本发明制备的材料在性质上具有类似于“CdO”增强相的高温分解特性；其纳米材料结构有助于增大纳米材料之间的有效接触面积，拥有比SnO2增强相更高的导电特性，从而可以有效改善银基电接触材料电学性能。本发明产品形貌、尺寸可控，可以有效改善电接触材料电学、热学性能，且反应合成条件简易、成本低廉。
