Low-cost preparation method of multi-element transition metal boride powder
The invention discloses a low-cost preparation method of multi-element transition metal boride powder, and belongs to the technical field of ceramic materials. The method comprises the following steps: by taking micron-sized MoO3, WO3, Cr2O3, MOx, B4C and C as raw materials, mixing, drying and sieving raw material powder, and then carrying out heat treatment by utilizing pressureless sintering to obtain required boride powder. The preparation method comprises the following steps: firstly, wet-grinding and mixing transition metal oxides MoO3, WO3, Cr2O3, Ta2O5, B4C and C powder through swing ball milling, then sufficiently drying the uniformly mixed raw materials in a rotary evaporator, and finally, carrying out heat treatment on the uniformly mixed raw materials to prepare the high-entropy ceramic powder, and adjusting process parameters to obtain the high-entropy ceramic powder with a single-phase structure. According to the method, the boride high-entropy ceramic powder is successfully synthesized for the first time, and the synthesized (Mo0. 25W0. 25Cr0. 25M0. 25) B high-entropy ceramic powder has better particle dispersity and microstructure through multiple technical characterization.
本发明公开一种多元过渡金属一硼化物粉体的低成本制备方法，属于陶瓷材料技术领域。该方法包括采用微米级MoO3、WO3、Cr2O3、MOx、B4C和C为原料，将原料粉末混料、干燥、过筛后利用无压烧结进行热处理，得到所需一硼化物粉末。本发明首先通过摇摆球磨将过渡金属氧化物MoO3,WO3,Cr2O3,Ta2O5,B4C和C粉进行湿磨混合，然后将混合均匀的原料在旋转蒸发器中充分干燥，最后对混合均匀的原料进行热处理实现高熵陶瓷粉体的制备，通过调整工艺参数，获得单相结构的高熵陶瓷粉体。该方法首次成功合成出了一硼化物的高熵陶瓷粉体，通过多项技术表征，合成的(Mo0.25W0.25Cr0.25M0.25)B高熵陶瓷粉体具有较好的颗粒分散性和微观形貌。
