A method for producing an amorphous carbon particle includes the steps of: obtaining a first crosslinked product by admixing mesophase particles with an amorphous carbon precursor and thereafter subjecting the mixture to a crosslinking treatment, or obtaining a second crosslinked product by crosslinking the amorphous carbon precursor and thereafter admixing the mesophase particles with the crosslinked precursor; and subjecting the first or second crosslinked product to an infusibilization treatment and thereafter firing the product to produce amorphous carbon particles including the mesophase particles within the particles.

A method for producing amorphous carbon particles comprising includes adding and mixing graphite particles into a precursor of amorphous carbon and then cross-linking the precursor of amorphous carbon to obtain a first cross-linked product, or cross-linking a precursor of amorphous carbon and then adding and mixing graphite particles into the cross-linked precursor of amorphous carbon to obtain a second cross-linked product. Infusibility is imparted to the first or second cross-linked product to obtain an infusibilized product to which infusibility has been imparted. The infusibilized product is baked to obtain amorphous carbon particles. The amorphous carbon particles include the graphite particles and amorphous carbon which embeds the graphite particles.

A method for producing a non-graphitizable carbon material includes providing a raw material of a non-graphitizable carbon material. The raw material is cross-linked to obtain a cross-linked product. The cross-linked product is infusibilized to obtain an infusibilized product. The infusibilized product is baked to obtain the non-graphitizable carbon material. A mechanochemical treatment is performed on the cross-linked product or the infusibilized product.

A method for producing a carbonaceous powder which can be used as dielectric fine particles to be dispersed in an insulating oil to produce an electrorheological fluid is provided. The method comprises the steps of subjecting a starting organic material selected from the group consisting of coal, coal tar, coal tar pitch, liquefied coal, coke, petroleum, petroleum tar, petroleum pitch, and resins to a heat treatment at a maximum temperature of 300.degree. to 800.degree. C. to produce carbonaceous material; pulverizing and classifying the material to produce carbonaceous particles having a mean particle size of 0.5 to 40 .mu.m and a maximum particle size of up to 50 .mu.m; and subjecting the particles to an additional treatment at an elevated temperature and/or a reduced pressure, said additional treatment being carried out at a temperature lower than said maximum temperature of the heat treatment. The resulting carbonaceous powder may optionally be subjected to a further pulverization treatment.
