A Raman spectroscopic in situ study of binder systems for carbon-bonded filters



Environmentally friendly binder systems for carbon-bonded filters

based on lactose/tannin were investigated by Raman spectroscopy. In

earlier samples, CarboresP was used as a binder, which is replaced

by a lactose/tannin mixture in this work. With Raman spectroscopy,

the size of sp² carbon clusters using the intensity ratio of the D- and

G-bands can be qualitatively obtained.

In situ measurements under argon atmosphere for the pure substances

lactose, tannin and CarboresP were performed while heating the

samples. The same measurements were carried out on the mixed

binder system as well. The obtained sizes of the graphite-like clusters

were compared with the results from pre-annealed samples.

The Raman spectroscopy at high-temperatures was complemented by

high-temperature X-ray diffraction.
