An object is to provide a production method that is a method for producing a spherical particle material by a melting method and that makes a melting spheroidization ratio higher than the conventional method. A production method for a spherical particle material of the present disclosure achieving the above object includes: a raw particle material preparation step of preparing a raw particle material composed of an inorganic material; and a spheroidization step of feeding the raw particle material into a high-temperature atmosphere to melt the raw particle material and then rapidly cooling the raw particle material to prepare a spherical particle material having a volume average particle diameter of 1 m or more and less than 10 m, and a powder compressibility evaluation FF value, by a powder rheometer, of the raw particle material is 2.0 or more.

The addition of graphene to the pelletizing of carbon black during carbon black's manufacturing can allow a higher level of dispersion and exfoliation of the graphene when carbon black is compounded in rubber. This is applicable to pelletization of all grades of carbon black with all classes of graphene such as graphene oxide, reduced graphene oxide, and pure graphene, and which any graphene organic functionality will have minimal effect. Amounts of graphene incorporated into the carbon black pellets will be from about 0.01 weight percent to about 30 weight percent, including as an example, between about 0.03 and about 6 weight percent. The use of carbon black as a carrier will mitigate graphene dusting (safety benefits), maximize dispersion in a rubber compound (processing benefits), and facilitate full attainment of rubber compound material properties through the inclusion of graphene (performance benefits).
