A method for producing a carbon particle by a detonation method includes two steps. The first step is a step of disposing an explosive substance in the periphery of a raw material substance. The explosive substance has a detonation velocity of 6,300 m/s or more. The raw material substance contains an aromatic compound having not more than 2 nitro groups. The second step is a step of allowing the explosive substance to detonate.

Detonation-mediated carbon particle production method

A production method of a carbon particle by a detonation method includes a step of disposing an explosive substance in a periphery of a raw material substance, and a step of subjecting the explosive substance to a detonation. The explosive substance is a liquid at normal temperature and normal pressure. The raw material substance contains an aromatic compound having 3 or more nitro groups.

Method for producing carbon particles by detonation

Provided is graphite group that, when observed with a transmission electron microscope, has a laminated surface spacing of 0.2-1 nm, includes graphite pieces measuring 1.5-10 nm in a direction perpendicular to the laminating direction, the laminating direction of the graphite pieces being irregular.

Graphite group, carbon particles containing said graphite group

A blast treatment method whereby a smoke grenade is blast treated inside an explosion-proof container, said method comprising: a blast step in which the smoke grenade () is exploded inside the explosion-proof container (); and a dissolving step in which gas or micro particles generated when the smoke grenade () was exploded are dissolved inside the explosion-proof container (), in a liquid (W) including a greater volume of water than the volume of water generated by the explosion of the smoke grenade ().

Blast treatment method

A blast treatment method capable of more reliably treating an object to be treated which is accommodated in an outer container is provided. The blast treatment method includes: a step for spacing a plurality of blasting explosives () from one another at positions on the outer side surface of an outer container () in a direction surrounding a central axis (C) of the outer container () and arranging the blasting explosives () in such a manner as to extend approximately parallel to the central axis (C); a step for installing the outer container () within a chamber (); and a step for detonating the blasting explosives () within the chamber to perform blast treatment of an object () to be treated with the detonation energy, wherein the blasting explosives () are detonated at the blast timing at which fragments of the outer container () or shock waves, which are generated in the vicinity of the blasting explosives () by the detonation energy of the blasting explosives (), collide with or propagate to a bombshell () in less time difference than that in the case in which the plurality of blasting explosives () are detonated at the same time.

Blast treatment method and blast treatment device

An aspect of the present invention is a method of processing a waste material that contains mercury or a mercury compound, and chlorine or a mercury chloride, the method including a step of adding a chlorine scavenger to the waste material, and stowing the waste material in a treatment vessel; and a step of subjecting the waste material to a blasting treatment by fitting an explosive to the treatment vessel and detonating the explosive inside a pressure-proof container.
