【摘要】 将天然沸石应用到耐火材料领域中，以天然沸石为主要原材料、TiO₂和WO₃作为添加剂、活性炭作为造孔剂，采用部分烧结的方法制备多孔陶瓷。主要探讨了不同烧结温度（600、800和1 000℃）和活性炭比例（0、5%和10%）对多孔陶瓷的显气孔率、耐压强度、物相组成和微观形貌的影响。结果表明：烧结后试样的主要物相由TiO₂、CaWO₄和石英构成，试样的物相随温度升高没有显著的改变。当活性炭比例为10%、烧结温度为1 000℃时，试样具备最佳的物理性能，显气孔率为50.39%,耐压强度为3.78MPa。旨在为采用天然沸石制备多孔陶瓷提供有价值的理论指导。更多还原

【Abstract】 Natural zeolite was applied to the field of refractory materials, and porous ceramics were prepared by partial sintering with natural zeolite as the main raw materials, TiO₂ and WO₃ as additives, and activated carbon as pore making agents. The effects of different sintering temperatures（600, 800 and 1 000 ℃） and activated carbon ratios（0, 5% and 10%） on porosity, compressive strength, phase composition and micromorphology of porous ceramics were mainly discussed. The results showed that the main phase of the sample after sintering was composed of TiO₂, CaWO₄ and quartz, and the phase of the sample did not change significantly with the increase of temperature. When the proportion of activated carbon was 10% and the sintering temperature was 1 000 ℃, the sample showed the best physical properties, with a porosity of 50.39% and a compressive strength of 3.78 MPa. It aims to provide valuable theoretical guidance for the preparation of porous ceramics using natural zeolite.更多还原
