| titleOfInvention | SYNTHESIS AND CHARACTERIZATION OF SUPERPARAMAGNETIC APPLICANTS BY THE METHOD OF COATING IN WATER SOLUTIONS |
| abstract | The present invention relates to the synthesis and characterization of superparamagnetic nano-particles by a co-precipitation method in aqueous solutions with a narrow particle size distribution between 5 nm and 100 nm, with a specific magnetization of 10 to 70 Am2 / kg with the applied magnetic field strength less than 0 , 25 mT, characterized in that the composition of metal cations Fe, Fe, Mn, Zn, Co, based on sulphates, chlorides, nitrates and acetates in a concentration range of 0.01 to 2 mol / l, precipitation reagents of NaOH, KOH, NH4OH, (CH3) 4N + OH-, in a concentration range of from 0.1 to 15 mol / l and process parameters, the reaction temperature ranges from 20 to 120 degrees Celsius, reaction time in the range of l minute to 5 hours, and the pH of the reaction in range 3 up to 12. The final properties of super paramagnetic nano-particles are determined by the ratio of the basic components of metal cations and precipitation reagents, the associated process parameters (temperature, time, pH value) and the specific surface area (A BET) of nanoparticles, nano-particle size calculated on the basis of BET (D BET), x-ray powder diffraction of nanoparticles (D XRD) and specific magnetization (sigma S) of nano-particles. Nano-materials based on super paramagnetic nano-particles allow the creation of new devices and systems and the exploitation of new phenomena in nano-dimensions in the fields of biomedicine (diagnostics, therapy, targeted transfer of active substances, ...), biotechnology (gene therapy, cell separation,. ..), environmental protection (separators, ..) and industrial applications (sealing, damping, heat transfer, separation, sensors, ...). |
