Effect of Al<inf>2</inf>O<inf>3</inf> on the morphological and gas sensing properties of SnO<inf>2</inf> pellets


Alumina mixed tin oxide (SnO<sub>2</sub>: Al<sub>2</sub>O<sub>3</sub>) powders were obtained by employing chemical and physical synthesis methods. The powders were prepared from tin chloride as Sn source, urea (R1) and ammonia (R2) as precipitant agents. The resultant SnO<sub>2</sub> powders are milled in a planetary ball mill. Finally, Al<sub>2</sub>O<sub… (More)
