Silicon carbide ceramic microsphere as well as preparation method and application thereof
The invention discloses silicon carbide ceramic microspheres as well as a preparation method and application thereof, and relates to the technical field of ceramic powder preparation. The silicon carbide ceramic microspheres are spherical or nearly spherical in appearance, the diameter is 20-200 microns, the density is 2.9-3.1 g/cm < 3 >, and the preparation process mainly comprises four processes of dispersing, granulating, screening and densifying. The silicon carbide ceramic microspheres are spherical or nearly spherical in appearance, and compared with irregular angular silicon carbide powder, the silicon carbide ceramic microspheres are good in fluidity and high in stacking density no matter the silicon carbide ceramic microspheres are dry powder or prepared into ceramic slurry or viscoplastic materials. The problems that existing ceramic powder is low in stacking density and poor in density uniformity are solved.
本发明公开了一种碳化硅陶瓷微球及其制备方法和应用，涉及陶瓷粉体制备技术领域。该碳化硅陶瓷微球外形呈球状或近球状，直径为20‑200μm，密度为2.9‑3.1g/cm3，本发明制备过程主要分为分散、造粒、筛分和致密化四个过程。本发明的碳化硅陶瓷微球外形呈球状或近球状，不管是干粉，还是将其配制成陶瓷浆料，或粘塑性料，相比不规则棱角状碳化硅粉，其流动性要好，堆积密度要高。本发明解决了现有陶瓷粉料的堆积密度低和密度均匀性差的问题。
