（1）Abstract : The properties of sensors manufactured by strong pressing of SnO2 (stannic oxide) have been studied. The correlation between the pressing pressure of SnO2 and sensitivity and stability was established. The results show that when the pressing pressure of SnO2 increases, the stability of sensors increases too, but the sensitivity strongly decreases. The best sensors performance is achieved by strong pressing (4000MPa) of SnO2 with 40wt.% content of Al2O3. (alumina)
