Özet:

 


The extraction and characterization studies were carried out on representative samples
which were taken from iron bearing parts of halloysite, halloysite/kaolin deposits located in the vicinity
of Çanakkale and Balıkesir in Northwest Anatolia. Halloysites in these samples are generally in the
form of hydro halloysite (10 Å) and kaolinite could also be encountered in some parts. The primary
impurities in halloysite and kaolin deposits are limonite (geothite) and muscovite. These deposits might
contain quartz, feldspar, gibbsite, smectite group clay minerals and anatase in their structures. The
iron content of the clays can be reduced significantly by hydrochloric or oxalic acid treatments. Transmission
electron Microscope (TEM) and Scanning Electron Microscope (SEM) analyses on halloysite
samples were carried out and it was noticed that halloysite tubes were in cylindrical shape, and in
some cases; pores on their surfaces could be observed as a structural feature. In samples studied,
tube lengths were measured up to 5 µm by means of SEM analyses, however; TEM analyses have
indicated that internal diameters of tubes could decrease down to 5nm and their average diameters
ranged in between 40 – 50 nm.
