Abstract The alkali agent according to the present invention is characterized by including magnesium oxide particles having a crystallite diameter of 80-300 nm, a BET specific surface area of 0.1-1.2 m2/g, and an MgO content of 95.0 mass% or higher. (The MgO content is a value with respect to the total content (mass%) of five elements, Mg, Ca, Si, Fe, and Al, detected by fluorescent X-ray spectroscopy, in terms of MgO, CaO, SiO2, Fe2O3, and Al2O3 amounts respectively, which is taken as 100.) L'agent alcalin selon la présente invention est caractérisé en ce qu'il comprend des particules d'oxyde de magnésium ayant un diamètre de cristallite de 80 à 300 nm, une surface spécifique BET de 0,1 à 1,2 m2/g, et une teneur en MgO supérieure ou égale à 95,0 % en masse. (La teneur en MgO est une valeur par rapport à la teneur totale (% en masse) de cinq éléments, Mg, Ca, Si, Fe et Al, détectés par spectroscopie de rayons X fluorescents, en termes de quantité de MgO, CaO, SiO2, Fe2O3, et Al2O3 respectivement, qui est prise comme 100.) 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。)
