PURPOSE:The titled lubricant with mild gradient of specific resistance as compared with carbon powder having finely adjustable specific resistance, which is prepd. by mixing a lubricant with an antimony-contg. tin oxide powder. CONSTITUTION:A liquid, solid or semisolid lubricant such as paraffin-base grease consisting of an org. material is mixed with 5-50wt.% tin oxide powder of average particle size <=1.0mu contg. 0.1-20wt.% antimony. EFFECT:A lubricating oil of specific resistance 10<7>-10<11> is obtd. USE:A lubricant for a tuning knob of a cassette tape recorder, radio, etc. |
