The effect of variations in calcination temperature and time, solution concentration, and spraying pressure on the surface area of alumina was studied. Increasing the calcination temperature and time results in a decrease in surface area, whereas increasing the solution concentration and spraying pressure for a given nozzle diameter increases the surface area.
