Abstract

Abstract: SiC is a high-performance structural material.The key to prepare high-quality and low-cost SiC green bodies via the colloidal forming method is to obtain slurries with low viscosity and high solid content.The type,combination,and addition of dispersants directly determine the stability and rheological properties of the slurries.Therefore,the effects of single dispersant and mixed dispersant on the stability and rheology of SiC ceramic slurries were reviewed.The three stabilization mechanisms:electrostatic stabilization,steric stabilization,and electrosteric steric synergistic stabilization,were briefly described,aiming to provide a theoretical reference for subsequent research on optimizing the performance of SiC slurries.

Key words: SiC powder, dispersant, stability, rheology

摘要： SiC陶瓷作为高性能结构材料,通过胶态成型法制备高品质、低成本坯体的关键在于获得低黏度、高固含量的浆料。分散剂的种类、复配方式及添加量直接决定浆料的稳定性与流变性能。为此,综述了单一分散剂及混合分散剂对SiC陶瓷浆料稳定性和流变性的影响研究现状,简述了静电稳定、空间位阻稳定及静电-空间位阻协同稳定三大机制,旨在为优化SiC浆料性能的后续研究提供理论参考。
