| description | To provide an alkali agent having a moderate elution speed and exhibiting a stable effect over a long period.SOLUTION: An alkali agent comprises magnesium oxide particles having a crystal diameter of 80-300 nm, a BET specific surface area of 0.1-1.2 m2/g, and a MgO content of 95.0 mass% or more. (The MgO content is the value obtained when 5 elements of Mg, Ca, Si, Fe, and Al, detected by X-ray fluorescence measurement, are converted into MgO, CaO, SiO2, Fe2O3, and Al2O3, respectively, and the total content (mass%) is 100).SELECTED DRAWING: None
【課題】適度な溶出速度を有し、長期にわたって安定した効果を発揮可能なアルカリ剤を提供する。【解決手段】本発明に係るアルカリ剤は、結晶子径が８０～３００ｎｍ、ＢＥＴ比表面積が０．１～１．２ｍ２／ｇであって、ＭｇＯ含有率が９５．０質量％以上である酸化マグネシウム粒子を含有することを特徴とする。（ＭｇＯ含有率は、蛍光Ｘ線測定にて検出されたＭｇ，Ｃａ，Ｓｉ，Ｆｅ，Ａｌの５元素を、それぞれＭｇＯ、ＣａＯ、ＳｉＯ２、Ｆｅ２Ｏ３、Ａｌ２Ｏ３に変換した際の含有率（質量％）合計を１００としたときの値である。）【選択図】なし |
