Efficient infiltration ceramic slurry and preparation method thereof
According to the efficient infiltration ceramic slurry and the preparation method thereof, silicon carbide ceramic powder with the particle size being 300-500 nm is used in the preparation process, and the silicon carbide ceramic powder in the slurry cannot rapidly and spontaneously sink in a system due to the fact that the particle mass is too large; the silicon carbide particles are dispersed in water in a relatively long time range by utilizing electrostatic repulsion of the surfaces of the particles when the particles are dispersed in the water and a steric hindrance stabilization effect of dispersing agent macromolecules, so that the slurry with low viscosity and high solid content is obtained for infiltration.
本发明公开了一种高效浸渗的陶瓷浆料及其制备方法，其中在制备过程中使用了粒径为300‑500nm的碳化硅陶瓷粉末，该碳化硅陶瓷粉末在浆料中，既不会因颗粒质量过大而在体系中快速地自发下沉，又不会因为比表面积过大在体系中迅速团聚发生沉降，同时利用粒子分散在水中时表面的静电斥力和分散剂大分子的空间位阻稳定效应，使得碳化硅粒子在较长的时间范围内在水中稳定的分散，得到低粘度高固相含量的浆料进行浸渗。
