以偏高岭石、石英和消石灰为原料，采用不同的成型压力，通过水热处理制备了介孔材料。水热固化的材料发展的强度，尽管形成水石榴石。水热固化材料具有大于3.4nm的宽孔径分布，并且体积和比表面积随着成型压力的降低而增加。水热固化材料显示出优异的湿度控制能力，由于吸附和解吸的水蒸气，利用其介孔。
Mesoporous materials were prepared by hydrothermal treatment of powder-compacts consisting of metakaolinite, quartz and slaked lime with different forming pressures. The hydrothermally solidified materials developed strength despite the formation of hydrogarnet. The hydrothermally solidified materials exhibited a broad pore size distribution of more than 3.4nm, and the volume and specific surface area increased with decreasing the forming pressure. The hydrothermally solidified materials showed an excellent humidity-controlling ability due to adsorption and desorption of water vapor by utilizing their mesopores.
