Abstract: The semiconducting SnO2 powder sized in 0.02~10μm was degassed completely in high vaccum and pressurized at above 40MPa to give repeatable values of d.c. resistance. For SnO2 undoped by Sb the d.c. resistance values obtained were changed with the cooling process used. The results have been discussed in terms of the structure of the polycrystalline of SnO2.

Key words: tin oxide powder, d.c. resistance, determination
