<P>PROBLEM TO BE SOLVED: To provide a method for producing a powder which can control the strength of the resultant powder and can produce a powder with uniform hardness, the powder produced by the method and an adsorption apparatus provided with the powder. <P>SOLUTION: The method for producing the powder has a first step of preparing a slurry containing the aggregate of a synthetic material obtained by reacting a first liquid containing a first raw material with a second liquid containing a second raw material while stirring, a second step of keeping the stirring of the slurry containing the aggregate and a third step of preparing the powder of the synthetic material by drying the slurry. It is characterized in that an initial temperature to react the first liquid with the second liquid is established in the first step and the strength of the powder is controlled by establishing the condition of the stirring of the slurry in the second step. <P>COPYRIGHT: (C)2011,JPO&INPIT |
