Porous silicon nitride ceramic with complex structure as well as rapid preparation method and application of porous silicon nitride ceramic
The invention discloses a porous silicon nitride ceramic with a complex structure and a rapid preparation method and application of the porous silicon nitride ceramic, and belongs to the technical field of inorganic non-metallic material preparation. The porous silicon nitride ceramic with the complex structure is rapidly prepared through slurry preparation, 3D printing forming and combustion synthesis. Porous silicon/silicon nitride green bodies in any complex shapes can be manufactured by means of the 3D printing technology, continuous nitridation of silicon powder in the green bodies is guaranteed through energy released during combustion of the green bodies, near-zero-energy-consumption efficient sintering of the green bodies can be achieved, complex high-temperature and high-pressure equipment does not need to be used, and the production cost is reduced. The method has the advantages of simple process, good repeatability, high yield, low cost, low energy consumption, short period and the like. The invention provides a new thought and a new method for design and preparation of porous ceramics with complex structures, and is expected to widen the application field and range of the materials.
本发明公开了一种复杂结构多孔氮化硅陶瓷及其快速制备方法和应用，属于无机非金属材料制备的技术领域，本发明采用硅粉和氮化硅粉作为主要原料，添加烧结助剂和粘结剂，通过配制浆料、3D打印成型和燃烧合成快速制备复杂结构多孔氮化硅陶瓷。其中，借助3D打印技术能够制造任意复杂形状的多孔硅/氮化硅生坯，而生坯燃烧时释放的能量不仅保证了其中硅粉的持续氮化，而且能实现其近零能耗高效烧结，无需使用复杂的高温、高压设备，具有工艺简单、重复性好、产量高、成本低、能耗低、周期短等优点。本发明为复杂结构多孔陶瓷的设计制备提供了新思路和新方法，有望拓宽该类材料的应用领域和范围。
