Micro-nano TiCN powder as well as preparation method and application thereof
The invention provides micro-nano TiCN powder as well as a preparation method and application thereof. Nano titanium oxide, nano carbon black and titanium powder are taken as raw materials, mixing andball milling are conducted, carbonization is conducted under the nitrogen pressure maintaining condition, and the micro-nano TiCN powder is prepared. According to the method disclosed by the invention, nano titanium oxide and nano carbon black are used as raw materials, so that the contact area between reactants can be increased, and the rate of carbon thermal nitriding reaction can be increased, thereby shortening the reaction time to a certain extent, reducing the reaction temperature and correspondingly reducing the opportunity of particle size growth of the product. Titanium powder is used as an additive to accelerate the reaction degree. The raw material mixture is subjected to mechanical ball milling, so that the raw material powder is more uniform and further amorphous, and the reaction degree can be increased in the carbonization process.
本发明提供一种微纳米级TiCN粉体及其制备方法与应用。以纳米氧化钛、纳米炭黑和钛粉为原料，混合球磨，氮气保压条件下进行碳化，制备出微纳米级TiCN粉体。本发明方法以纳米氧化钛和纳米炭黑为原料，可以增大反应物之间的接触面积，加快碳热氮化反应的速率，从而可以在一定程度上缩短反应时间，降低反应温度，相应也就减少了产物粒度长大的机会。以钛粉作为添加剂，加速反应程度。采用机械球磨原料混合物使原料粉体更均匀和更进一步的无定形化，从而在碳化过程中可以加速反应程度。
