摘　　要：Effects of starting materials and four dispersants （ STP, SHP, FDN and FS60 ） on Zeta potential and rheological behavior of alumina based ULC castables matrix were investigated. The results show that： characteristics of silica fume and alumina cements play a very important role in Zeta potential and viscosity of suspensions of the castables matrix; the dispersants STP and SHP can change Zeta potential values of the matrix suspensions remarkably; the four dispersants can effectively improve the rheological properties of matrix suspensions. For the point of lower viscosity of the matrix suspensions, the suitable additions of the three dispersants （ SHP , FDN and FS60 ） are about 0. 2% while that of STP is about 0. 3%.Effects of starting materials and four dispersants （ STP, SHP, FDN and FS60 ） on Zeta potential and rheological behavior of alumina based ULC castables matrix were investigated.
