Title:
CARBON FLUORIDE PARTICLES, PROCESS FOR PRODUCING THE SAME, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/1994/011301
Kind Code:
A1
Abstract:
Carbon fluoride particles wherein the number-average particle diameter is 0.01-50 mum, the content of particles having such diameters that the particle size distribution thereof falls within the range from the number-average particle diameter minus 20 % to the number-average particle diameter plus 20 % amounts to at least 50 % of the whole, the true specific gravity is 1.7 to 2.5, the F to C ratio of the particle as a whole is 0.001 to 0.5, and the F to C ratio at the surface of the particle is invariably greater than that of the particle as a whole and is 0.1 to 2.0. The carbon fluoride particles can be produced by the reaction of carbon particles with fluorine at 350-600 �C for 1 minute to 6 hours. The obtained particles have excellent dispersibility and powder fluidity and are used as such or in the form of composite material as water- and oil-repellent, detackifying agent, solid lubricant, conductivity improver, additive for electrostatic development toner, additive for resinous coating layer of electrostatic development carrier, composite material for fixing roller, phosphate-type fuel cell, air/zinc battery and nickel/hydrogen storage battery.
