摘要/Abstract

摘要： 以Si为基体,配成三种料浆体系:(1)100wt%Si (2)5wt%Si_3N_4、95wt%Si(3)5wt% Si_3N_4、10wt%SiC、85wt%Si.利用流变仪研究了改变各个体系的磷酸三乙酯分散剂含量以及pH值时,各个体系流变性的差异.实验结果发现:Si悬浮粒子的等电点在pH=3.1;加入分散剂和改变pH值能明显改善Si基浆体的流变性,分别得到最佳分散剂含量以及pH值.

关键词: Si粉;浆体;流变性;分散剂;pH值

Abstract: Three kinds of Si-based slurries:(1)100wt%Si(2)5wt%Si_3N_4,95wt%Si(3)5wt% Si_3N_4,10wt%SiC,85wt% Si were synthesized.The rheological behaviors of Si-based slurries were investigated by changing additions of(C_2H_5O)_3PO and pH value.The results showed that the isoelectric point (IEP) of Si is around pH value of 3.1.The rheological behaviors of the slurries with different additions of(C_2H_5O)_3PO and at different pH could be significantly improved;the best content of (C_2H_5O)_3PO and the best pH were known respectively.
