The correlation between the pressing pressure of SnO2and sensitivity and stability was established. The results show that when the pressing pressure of SnO2increases, the stability of sensors increases too, but the sensitivity strongly decreases. The best sensors performance is achieved by strong pressing (4000MPa) of SnO2with 40wt.% content of Al2O3.
