直接凝固注模成型SiC陶瓷──浆料凝固过程的研究

Direct Coagulation Casting of SiC-the Solidification Process

直接凝固注模成型是一种新的（准）净尺寸成型陶瓷部件的方法，本文主要研究了此方法的关键步骤一浆料凝固过程，高固相含量（＞５５ｖｏｌ％）浆料从可浇注的低粘度状态转变为有一定强度的凝固态（坯体）主要有两种方法，即增加浆料中的电解质浓度和移动浆料的ｐＨ值至等电点。

Direct Coagulation Casting (DCC) is a new colloidal method for ceramic shape forming.The solidification process of SiC slurry for shape forming by DCC was investigated in this process. The solidification of a highly concentrated slurry with low viscosity was performed by increasing the ionic concentration or. shifting the PH to Isoelectric Point.
