Abstract
Przedmiotem zgłoszenia jest sposób otrzymywania nanokrystalicznych cząstek żelaza o średniej wielkości krystalitów do 100 nm pokrytych monowarstwową otoczką grafenową z wykorzystaniem procesu segregacji węgla z roztworów Fe-C, polegający na tym, że nanokrystaliczne żelazo z ilością wynoszącą od 3 do 7% wagowych tlenków trudno redukowalnych takich jak Al2O3, CaO, MgO, poddaje się procesowi redukcji, a następnie nawęglania lub jedocześnie procesowi redukcji i nawęglania, przy czym proces redukcji i nawęglania prowadzi się w zakresie temperatur od 300 do 700°C do momentu uzyskania roztworu węgla w żelazie, po czym prowadzi się proces wygrzewania tak powstałej próbki w temperaturze niższej od temperatury nawęglania.The subject of the application is a method of obtaining nanocrystalline iron particles with an average size of crystallites up to 100 nm covered with a monolayer graphene coating using the process of segregation of carbon from Fe-C solutions, consisting of the fact that nanocrystalline iron with an amount of 3 to 7% by weight of hardly reducible oxides such like Al2O3, CaO, MgO, it undergoes a reduction process followed by carburizing or simultaneously a reduction and carburizing process, the reduction and carburizing process being carried out in the temperature range from 300 to 700 ° C until a carbon solution in iron is obtained, then the process of heating the sample thus formed at a temperature lower than the carburizing temperature.
