Abstract

The effects of surface dehydration on textural properties, crystallinity and the structure of AlPO4−ZrO2 (weight ratio AlPO4/ZrO2=3) systems precipitated with ethylene oxide have been studied by N2 adsorption and XRD measurements. The increase in calcination temperature in the range 773–1273 K decreases the textural parameters as a consequence of AlPO4 crystallization to the tridymite form.

Abstract

Влияние дегидрирования поверхности на текстурные свойства, кристалличность и структуру систем AlPO4−ZrO2 (весовое соотношение AlPO4/ZrO2=3), высажденных окисью этилена, исследовали адсорбцией N2 и рентгено-дифракционными измерениями. Увеличение температуры обжига от 773 до 1273 К уменьшает текстурные параметры, что является следствием кристаллизации AlPO4 в тридимитную форму.
