摘要： 粒径为0.02～10μm的半导体氧化锡粉末在真空中充分脱气和施加高于40MPa压力可获得重现性较好的直流电阻。无锑掺杂氧化锡粉末的直流电阻随试样冷却吸附的温度而异,讨论了多晶氧化锡粉末的结构对电阻测定的影响。

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
