Summary

Column chromatography is a versatile tool for the investigation of the interaction between modified surfaces and organic additives which are interesting for ceramic processing. Dependence of retention time from polarity of eluents or test compounds allows conclusions on the polarity of the surface. Effects unwelcome in analytical or preparative chromatography, like strong absorption and chemical reactions, can be easily observed and give further information. The results obtained in chromatography fit very well with the observations of the compaction behavior of silicon nitride powders modified identically. Thus, column chromatography supports the choice of powder modification as well as of organic additives for ceramic processing.
