Process for producing a powder material for an electro-rheological fluid |
摘要 |
A process for producing a powder material for an electro-rheological fluid is provided. The powder material is advantageously used for an electro-rheological fluid having a property, such as viscosity, which changes by application of an electric field. A powder material for an electro-rheological fluid having a uniform distribution of particle diameters and a uniform distribution of electric conductivity can be produced by embrittling a carbonaceous powder material, pulverizing and classifying the embrittled carbonaceous powder material to obtain a carbonaceous powder material having a uniform distribution of particle diameters, and carbonizing the powder material under an atmosphere of an inert gas.
