Compressibility, pressure-induced amorphisation and thermal collapse of zeolites

摘要: High-pressure powder diffraction is used to follow the collapse of zeolite-A at ambient temperature and this compared with exotherms obtained from differential scanning calorimetry, when pressure induced high temperatures Constraint theory discussed in relation these zeolitic densification processes a simple model introduced The fraction floppy modes created during linked heat released zeolite collapses It argued that or crystalline structure coincides rigidity percolation threshold amorphisation follows constraint reassembly
