摘要：
The aggregation and phase separation of inorganic particles are performed in a sol containing the inorganic particles and a solvent to produce a porous body having open pores. Preferably, the inorganic particles are particles of one or more inorganic material selected from the group consisting of titania, silica, alumina, zinc oxide and zirconia. Further, the sol may have strong acidity and the pH of the sol is elevated to perform the aggregation and phase separation of the inorganic particles. Alternatively, the sol may have strong basicity and the pH of the sol is lowered to perform the aggregation and phase separation of the inorganic particles. The present invention provides a novel method of producing a porous body and sintered body having co-continuous structure, applicable to a wide variety of inorganic materials.
摘要（中）：
无机颗粒的聚集和相分离在含有无机颗粒和溶剂的溶胶中进行，以产生具有开孔的多孔体。 优选地，无机颗粒是选自二氧化钛，二氧化硅，氧化铝，氧化锌和氧化锆中的一种或多种无机材料的颗粒。 此外，溶胶可能具有强酸性，并且提高溶胶的pH以进行无机颗粒的聚集和相分离。 或者，溶胶可能具有强碱性，并且降低溶胶的pH以进行无机颗粒的聚集和相分离。 本发明提供一种生产具有共连续结构的多孔体和烧结体的新方法，适用于各种无机材料。
