Abstract
This method for producing a body obtained by processing a solid carbon-containing material includes: a step of preparing the solid carbon-containing material having at least a surface composed of solid carbon; and a step of processing the solid carbon-containing material. The step of processing the solid carbon-containing material includes: a sub-step of forming non-diamond carbon by heat-treating the solid carbon in the surface of the solid carbon-containing material; and a sub-step of removing at least a part of the non-diamond carbon.

A method for producing a body obtained by processing a solid carbon-containing material, the method comprising:
- a step of preparing the solid carbon-containing material having at least a surface composed of solid carbon;
- and
- a step of processing the solid carbon-containing material,
- wherein the step of processing the solid carbon-containing material includes:
- a sub-step of forming non-diamond carbon by heat-treating the solid carbon in the surface of the solid carbon-containing material;
- and
- a sub-step of removing at least a part of the non-diamond carbon,
- wherein a method for removing at least a part of the non-diamond carbon is at least one of
- a method for treating the non-diamond carbon with a gas phase fluid containing a gas containing at least one selected from the group consisting of an oxygen molecule, a hydrogen molecule, and a water molecule, by spraying the gas phase fluid onto the surface of the solid carbon-containing material from a fluid spraying part,
- a method for treating the non-diamond carbon with a gas phase fluid containing a plasma containing at least one selected from the group consisting of an oxygen atom, a hydrogen atom, a helium atom, and an argon atom, by spraying the gas phase fluid onto the surface of the solid carbon-containing material from a fluid spraying part, and
- a method for treating the non-diamond carbon with an ion beam containing at least one selected from the group consisting of an oxygen ion, a hydrogen ion, a hydroxide ion, a helium ion, and an argon ion, by irradiating the surface of the solid carbon-containing material with the ion beam from a beam radiating part,
- wherein at least one of
- the gas phase fluid containing at least one of the gas and the plasma is scanned by moving the fluid spraying part relative to the solid carbon-containing material, and
- the ion beam is scanned by moving the beam radiating part relative to the solid carbon-containing material.
A body obtained by processing a diamond-containing material, the body comprising a processed surface, at least a part of the processed surface being composed of diamond,
- wherein:
- the processed surface of the body obtained by processing a diamond-containing material has a smooth shape having a maximum height of less than or equal to 20 μm of small irregularities formed in the processed surface, or a shape having irregularities formed in a smooth surface in the processed surface and having a minimum height of greater than or equal to 30 μm;
- and
- the processed surface has a size of greater than or equal to 1 mm square, and a density of polishing damage points in the processed surface is 0 points/mm2.
