Abstract
Význam nano- a mikročástic v přírodních vědách je na vzestupu. Důležitá již dnes není jen jejich velikost nebo jejich měrný povrch, ale také stabilita, tvar, monodisperzita a elektrické nebo magnetické vlastnosti. Magnetické částice těchto rozměrů nalézají široká uplatnění v medicíně, analytické chemii i elektrotechnice. K těmto využitím jsou vybranou metodou syntetizovány čtyři druhy magnetických částic oxidů, které jsou následně charakterizovány. Jsou porovnány jejich syntézy a výsledné produkty. Chlorid sodný se v některých případech zdá být velmi vhodným stabilizačním činidlem, ale jeho efekt na výsledný produkt se oxid od oxidu liší.
Nano- and microparticles are more and more significant in natural sciences. Importance of their size or specific surface is currently being exceeded by their stability, shape, monodispersity and electric or magnetic properties. For magnetic particles of this size have been found many applications in pharmaceutical, analytical or electrochemical branches. For these usage possibilities were synthesized four types of magnetic oxide particles by a selected method and all products were tested subsequently. Their synthesis methods as well as the resulting products were compared. The effect of a sodium chloride on final products was investigated either as it appears to be a good stabilization agent, but its impact differs for different oxides.
