本研究研究了通过烧结火山灰、风化火山灰和废玻璃的混合物来生产湿度控制多孔陶瓷的可行性。测试了烧结条件，包括烧结时间、烧结温度和玻璃改性剂的各种混合部分。分析最终陶瓷的孔分布、孔体积、吸附和解吸特性以及弯曲强度。结果表明，火山灰陶瓷的孔径分布在70~100nm范围内，而风化火山灰陶瓷的孔径分布在7~9nm范围内。陶瓷的湿度控制条件利用了天然材料固有的孔隙率。两种情况下的弯曲强度均满足陶瓷断裂强度指标（>6Mpa）。
This study investigated the feasibility of generating humidity control porous ceramics by sintering a mixture of volcanic ash, weathered volcanic ash, and waste glass. The sintering conditions, including sintering time, sintering temperature, and various mixed portions of glass amendment, were tested. The final ceramics were analyzed for their pore distribution, pore volume, adsorption and desorption characteristics, and bending strength. The results indicate that the pore size of the volcanic ash ceramics tends to distribute in the range from 70 to 100nm, whereas that of the weathered volcanic ash ceramics is in the range of 7–9nm. The humidity controlling conditions of the ceramics take advantage of the inherent porosity of the natural materials. The bending strengths in both cases were all satisfying with the fractural intensity specification of ceramics (>6Mpa).
