Resumo

A new approach has been developed for the low-temperature synthesis of highly dispersed barium aluminate of vermicular morphology with specified characteristics (bulk density from 0.015 g/cm3, average particle size in the range of 15-87 nm). The synthesis technique includes sequential heat treatment up to 1200∘C of a concentrated aqueous solution of BaCl2, Al(NO3)3, (NH2)2CO and C6H8O7. Using physico-chemical research methods: IR spectroscopy, X-ray phase analysis, transmission and scanning electron microscopy, as well as chemical analysis, the main stages of the synthesis of BaAl2O4 are characterized.
