- Abstract (EN)
- Carbon-bonded alumina filters and their binders, lactose, tannin and CarboresP, were investigated by Raman spectroscopy. Special emphasis was placed on the pyrolysis study of the binders. In situ measurements were performed on the tannins gallic acid, ellagic acid and tannic acid to determine the pyrolysis temperatures and products. Furthermore, the binder samples fired in a reducing atmosphere in a coke bed were analyzed by Raman spectroscopy and their transition from an amorphous carbon system to nanocrystalline graphite was observed. The influence of different binders on the carbon-bound alumina filters was studied, as well as the influence of different additives. However, no significant difference was observed between samples with different binder compositions or with additives. In addition, Raman measurements on the spinel MgAlON indicate an increased disorder of the structure due to the incorporated nitrogen.
