Porous ceramics have been extensively investigated because of their high-temperature and chemical stabilities, which are far superior to those of porous polymers and porous metals, despite their mechanical instability. Among various kinds of porous ceramic, reticulated porous ceramics have attracted considerable attention because of their extremely high porosity, which is generally higher than 90% and can maximize the advantages of this class of materials. However, to the best of our knowledge, sufficient data are not available on the preparation of low-cost, abundant, and natural material-based reticulated porous ceramics. Therefore, we obtained and characterized reticulated porous diatomite–kaolin composites prepared under various processing conditions, such as solid loading, average particle size, and pore density. The experimental data were used to investigate whether the densities and compressive strengths of the reticulated porous diatomite–kaolin composite can be tailored, and to assess the potential of these materials in different application fields.

加工条件对网状多孔硅藻土-高岭土复合材料性能的影响

多孔陶瓷由于其高温和化学稳定性而被广泛研究，尽管它们具有机械稳定性，但远优于多孔聚合物和多孔金属。在各种多孔陶瓷中，网状多孔陶瓷由于其极高的孔隙率而引起了相当大的关注，孔隙率通常高于90％，并且可以最大化此类材料的优势。然而，据我们所知，尚无足够的数据可用于制备低成本，大量且基于天然材料的网状多孔陶瓷。因此，我们获得并表征了在各种加工条件下制备的网状多孔硅藻土-高岭土复合材料，例如固体载量，平均粒径和孔密度。
