Substrate-induced coagulation (SIC) of nano-disperse alumina in non-aqueous media: The dispersibility and stability of alumina in N-methyl-2-pyrrolidinone

▶ Development of a non-aqueous substrate-induced coagulation of nano-sized alumina. ▶ Zeta-potential and electrophoretic mobilities in polar, a-protic, non-aqueous media. ▶ Wetting behaviour characterised by powder contact angle and Wilhelmy plate method. ▶ Traces of water have an impact of stability of dispersions. ▶ Anionic surfactant does not stabilise non-aqueous alumina dispersions.
