Abstract

Calcination is a thermal process applied to solid materials to effect a thermal decomposition, a phase transition, or removal of a volatile component. A simple and inexpensive alcohol burner is used to replace an expensive furnace for the calcination process in this work. Titanium dioxide (TiO₂) nanoparticle synthesis was selected to demonstrate the use of the alcohol burner. X-ray diffractograms, TEM micrographs, and BET surface area analysis show that the TiO₂ powders obtained by such inexpensive calcination process can yield TiO₂ with comparable degree of crystallinity, smaller particle size, and higher specific surface area compared to commercial TiO₂ nanoparticles.
