Method for testing nanomaterials by means of determination of their physical and chemical properties

摘要

a research by defining their physicochemical properties of nanomaterials using programming techniques in chemical processes, characterised by the fact that in the processes azotowania or oxidation or coal usage in poland in the way programming changes, by changing the concentration reage nta gas potential respectively azotuju0105cy or oxidation or nawu0119glaju0105cy, in such a wayin order to determine the ru00f3wnowagowe and / or quasi ru00f3wnowagowe and subsequently measured known methods of chemical change in the solid phase.on the basis of the measured values for the characteristic parameters according to changes of the concentration of the reagent gas measuring method determines physicochemical properties of nanomaterial, such as changes in the composition of the phase, the average size krystalitu00f3w, fixed network.the degree of przereagowania chemical change is measured by termograwimetrycznu0105 or by measuring the consumption of reagent gas during the reaction or rentgenograficznu0105, or using spektrometrie: mass - to determine the chemical composition of gas; ftlr or ramanowsku0105 or moessbaureowsku0105 - specifying the structure of test; epr - in determining the magnetic characteristics of the substances to be tested.or the measurement of electrical conductivity.
