Preparation method of fiber composite boron carbide foamed ceramic material
The invention belongs to the technical field of preparation of inorganic materials, and discloses a preparation method of a fiber composite boron carbide foamed ceramic material, the preparation method comprises the following steps: preparing boron carbide powder into water slurry, sequentially adding an auxiliary agent, fiber, ammonium polymethacrylate and a binder in proportion to prepare a raw material solution, and then putting the raw material solution into a freezing device for directional freezing, and after complete freezing, drying to obtain a freeze-dried green body, and sintering in an argon flow atmosphere to obtain the fiber composite boron carbide foamed ceramic material. The process method is simple, low in energy consumption and free of pollution; the prepared boron carbide material is uniform and adjustable in pore diameter and orientation, and the pore structure can timely discharge byproduct helium absorbed by boron; the laminate-shaped structure is compact, and rays can be prevented from passing through without obstruction; the fibers are embedded into the laminates or are bridged between the adjacent laminates, so that the mechanical strength is enhanced, and the heat dissipation capability is improved. The prepared material can be used in the fields of nuclear power industry, protective armor and the like, and has a good application prospect.
本发明属于无机材料制备技术领域，公开了一种纤维复合碳化硼泡沫陶瓷材料的制备方法，即将碳化硼粉配成水浆料，按比例依次加入助剂、纤维、聚甲基丙烯酸铵和粘结剂制得原料液，之后将原料液放置于冷冻装置中进行定向冷冻，冷冻完全后干燥得到冻干坯体，在氩气流氛围烧结得到纤维复合碳化硼泡沫陶瓷材料。该工艺方法简单、能耗较低、无污染；制备的碳化硼材料孔径、取向均匀可调，孔结构可将硼吸收中子副产物氦及时排出；层板状结构致密，能够防止射线无阻碍穿过；纤维嵌入层板或桥连相邻层板间增强其机械强度、提高散热能力。制备的材料可用于核电工业、防护装甲等领域，具有良好的应用前景。
