18-11 OBłINEREA FILMELOR DE Fe2O3 PRIN METODA “SPRAY PYROLYSIS”

THE OBTAINING OF Fe2O3 BY SPRAY PYROLYSIS
The paper is a review of literature data related to iron oxide films
obtained from inorganic precursors using spray pyrolysis, an easy method
which does not involve high costs. The influence of deposition conditions on
structural and morphological properties is also presented.

18-13 PROPRIETĂłI OPTICE SI ELECTRICE ALE FILMELOR DE Fe2O3 OBłINUTE PRIN “SPRAY PYROLYSIS”

OPTICAL AND ELECTRICAL PROPERTIES OF Fe2O3
OBTAINED BY SPRAY PYROLYSIS
The paper is a review of literature data related to the optical and
electrical properties of iron oxide (Fe2O3) films. The main optical properties
studied were the transmittance, the absorption coefficient and the optical
bandgap. An important electrical property which was also presented was the
dark resistivity.

18-31 RECICLAREA CHIMICĂ A MATERIALELOR POLIMERICE

CHEMICAL RECYCLING OF POLYMERS
Excessive growth in recent years on the market of plastics materials
has increased the amount of wastes. Therefore, there were made a lot of
researches on plastics materials in order to establish an economically viable
method of recycling, with low environmental impact. A method that meets these
conditions and witch does not require any washing and separation of polymers
and/or waste materials based on these polymers, is the chemical recycling by
“pyrolysis”. By pyrolysis process, wastes are converted into liquid fractions
close to commercial fuels, in certain reaction conditions. The results obtained
are influenced by the temperature and catalysts that were used. The paper is a
review of literature data related to chemical recycling of polymers.
