| Summary: | It is well known that alumina possesses good mechanical and chemical
properties. Nanofibers having α - alumina structure was used as reinforcement
for metal, polymer and ceramic matrix composites. In this study, three series
of nanofibers were prepared. The first series was made from 10 % water
solution of the aluminium chloride hydroxide/polyvinyl alcohol with a mass
ratio of 5:1. The other two series were made with the addition of 1 wt.% of
MgCl2 or 1 wt.% of FeCl3 regarding the aluminium chloride hydroxide content.
Nanofibers were prepared using the electrospinning technique and they were
characterized by the TGA/DTA, XRD and FESEM methods. It was proven that
addition of FeCl3 into the initial spinning solution lowers the temperature
for the corundum structure formation while the addition of MgCl2 results if
the formation of mixed oxides that eases the sintering process. [Project of
