摘要: Abstract A novel and simple method to fabricate large-sized analcime (ANA) single crystals using the Geopolymer-Gels-Conversion (GGC) without organic template agents is reported. The results indicate that hydrothermal time plays an important role in determining size distribution. By controlling time, ANA with a diameter range of 50–1200 μm, icositetrahedron architecture can be synthesised. Due influence two silicon sources small surface area geopolymer bulk, crystallisation process, amorphous three-dimensional network structures Na 2 O–Al O 3 –4SiO geopolymers were converted into crystals.
