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.
