    • The invention pertains to a process for preparing a synthetic clay mineral which comprises silicon, aluminum, and at least one octahedron ion, which clay mineral has a total content of sodium and potassium of less than 0.5 wt. %, comprising the steps of a) providing a silica-alumina with a total content of sodium and potassium of less than 2.0 wt. % b) combining the silica-alumina with an octahedron ion source in such a manner that less than 0.1 mole of the total of sodium or potassium is added per mole of octahedron ion, c) if necessary, adjusting the pH to a value of at least 7, with less than 0.1 mole of the total of sodium and potassium being added per mole of octahedron ion during the pH adjustment, d) ageing the precipitate formed in c) at a temperature of 0-350° C. in an aqueous environment; e) optionally isolating the resulting material, optionally followed by washing. The invention makes it possible to prepare a saponite with a low content of sodium and potassium without an ion-exchange on the final material being necessary.
    • 本发明涉及制备包含硅,铝和至少一种八面体离子的合成粘土矿物的方法,该粘土矿物的钠和钾的总含量小于0.5wt。 %,包括以下步骤:a)提供总钠含量低于2.0重量%的二氧化硅 - 氧化铝。 b)将二氧化硅 - 氧化铝与八面体离子源结合,使得每摩尔八面体离子加入小于0.1摩尔的钠或钾的总量,c)如果需要,将pH调节至 至少7,在pH调节期间,每摩尔八面体离子添加少于0.1摩尔的钠和钾,d)在水溶液中在0-350℃的温度下老化c)中形成的沉淀物 ; e)任选地分离所得材料,任选地随后进行洗涤。本发明使得可以在最终材料上制备不含离子交换的钠和钾含量低的皂石。
