Análisis estructural del zeotipo JBW (Na-J, barrer y white) obtenido a partir de arcilla rica en caolinita
Resumen
La zeolita JBW fue preparada a partir de hidrogeles en condiciones hidrotérmicas por reacción alcalina, usando NaOH como agente activante. El zeotipo sintético se estudió por técnicas analíticas como difracción de rayos X en polvo, microscopía electrónica de barrido, espectroscopia infrarroja por transformada de Fourier y resonancia magnética nuclear de giro con ángulo mágico en estado sólido de 29Si y 27Al. Los datos cristalográficos revelan que la estructura JBW puede ser descrita por el grupo espacial ortorrómbico Pna21, con parámetros de celda unidad a=16.409(2) Å, b=14.966(2) Å y c=5.2154(5) Å.
