Porous aluminum nitride powder as well as preparation method and application thereof
The invention relates to the technical field of metallurgical materials, in particular to porous aluminum nitride powder and a preparation method and application thereof. The porous aluminum nitride powder comprises the following raw materials: aluminum nitride raw material powder, a binder, a grinding aid and a solvent, wherein the mass ratio of the aluminum nitride raw material powder to the binder to the grinding aid to the solvent is (30-70): (0-5): (0-5): (30-70); the structure of the porous aluminum nitride powder is a porous spherical structure; by designing the raw material composition of the aluminum nitride powder, the aluminum nitride raw material powder in the solvent can be completely dispersed with the binder and the grinding aid by the dispersing agent, the aluminum nitride raw material powder can be bonded and formed by the binder, and the crystal form of the aluminum nitride raw material powder can be ground by the grinding aid. The preparation method comprises the following steps: adding aluminum nitride raw material powder into the porous aluminum nitride powder, so that the shape of the aluminum nitride raw material powder is approximately spherical, and improving the pore ratio of the porous aluminum nitride powder through later calcination and decarburization, thereby obtaining the porous spherical aluminum nitride powder.
本申请涉及冶金材料技术领域，尤其涉及一种多孔氮化铝粉体及其制备方法和应用；所述多孔氮化铝粉体的原料包括氮化铝原料粉末、粘结剂、助磨剂和溶剂，氮化铝原料粉末、粘结剂、助磨剂和溶剂的质量之比为30～70：0～5：0～5：30～70；多孔氮化铝粉体的结构为多孔球形结构；通过设计氮化铝粉体的原料组成，分散剂可以将溶剂中的氮化铝原料粉体同粘结剂、助磨剂分散完全，粘结剂可以使得氮化铝原料粉体粘接成型，并通过助磨剂可以对氮化铝原料粉体的晶体形态进行打磨，使得氮化铝原料粉体的形态接近球形，再通过后期煅烧和脱碳，提高多孔氮化铝粉体的孔隙比例，从而得到多孔球形的氮化铝粉体。
