<P>PROBLEM TO BE SOLVED: To provide a mixed composition in which a mixture of an acidic powdered compound whose aqueous solution takes on acidic pH and an alkaline powdered compound whose aqueous solution takes on alkaline pH is improved so that a rapid continuous neutralization reaction may not occur in the atmosphere. <P>SOLUTION: The mixed composition is prepared by mixing a mixture of an acidic powdered compound and an alkaline powdered compound with a powdered neutralization reaction inhibitor in an amount required to inhibit the neutralization reaction of the acidic powdered compound and the alkaline powdered compound in the atmosphere at ≤70°C and a relative humidity of ≤90%, the inhibitor containing, as a principal component, one or more selected from among silicic acid (SiO<SB POS="POST">2</SB>), aluminum oxide (Al<SB POS="POST">2</SB>O<SB POS="POST">3</SB>), aluminum hydroxide (Al(OH)<SB POS="POST">3</SB>) and a stearate compound. <P>COPYRIGHT: (C)2012,JPO&INPIT |
