Synthesis of crystalline zeolite-13X from waste porcelain using alkali fusion

We attempted to convert waste porcelain into crystalline zeolite-13X using the alkali fusion method. Waste porcelain is mainly composed of amorphous glass phase and crystalline phases such as quartz and mullite. Most of the amorphous and crystalline phases were converted into soluble phases by alkali fusion, and could be transformed into single zeolite-13X crystals with a high specific surface area (412 m2/g) and unique micropore diameter (13 Å).
