Method of manufacturing inorganic material

A method of manufacturing an inorganic material, the method comprising:

• a step (A) of preparing a first inorganic material as a raw material;
• a step (B) of obtaining a second inorganic material by crushing the first inorganic material using a ball mill to obtain fine particles of the first inorganic material, the ball mill including a cylindrical container and crushing balls;
• and
• a step (C) of separating the second inorganic material from the crushing balls to which the second inorganic material is attached,
• wherein the step (B) includes a step (B1) of putting the first inorganic material and the crushing balls into the cylindrical container and subsequently rotating the cylindrical container about a cylindrical shaft and a step (B2) of moving the cylindrical container such that the first inorganic material moves in a cylindrical shaft direction
• wherein the step (B1) and the step (B2) are performed simultaneously, and
• wherein in the step (B2), the first inorganic material is moved in the cylindrical shaft direction by reciprocating at least one end of the cylindrical container in a direction perpendicular to the cylindrical shaft direction.
