    • A method for preparing a silica porous crystal, characterized in that it is a method for synthesizing a silica porous crystal through a hydrothermal reaction, which comprises forming a region having a high concentration of silicon in a part of a hydrothermal reaction vessel, and carrying out the hydrothermal reaction while allowing a bulk article comprising a compound containing silicon and oxygen and having been subjected to a surface-smoothing treatment, as a supply source of a part or all of the elements constituting the skeleton of the silica porous crystal, to be so present as for at least a part thereof to be within the above region having a high concentration of silicon. The above method allows the synthesis of a silica porous crystal having a size of 0.5 mm or more with good reproducibility and good efficiency.
    • 一种制备二氧化硅多孔晶体的方法,其特征在于它是通过水热反应合成二氧化硅多孔结晶的方法,其包括在水热反应容器的一部分中形成具有高浓度硅的区域,并进行 水热反应同时允许包含含有硅和氧的化合物并经过表面平滑处理的散装物品作为构成二氧化硅多孔晶体的骨架的部分或全部元素的供应源为如此 存在至少其一部分在具有高浓度硅的上述区域内。 上述方法允许以良好的再现性和良好的效率合成尺寸为0.5mm以上的二氧化硅多孔结晶体。
