Abstract

Mehanokemijska sinteza je sinteza inducirana vanjskom mehaničkom energijom, primjerice mljevenjem dviju ili više tvari u čvrstom stanju. Mehanička energija koja je primijenjena na krutinu uzrokuje kidanje jakih veza, što omogućuje tvorbu novih veza. Mehanokemijska sinteza omogućava sintezu bez otapala ili uz znatno smanjenu količinu otapala, čineći ju ekološki prihvatljivijom alternativom naspram klasičnih metoda sinteze. U ovom radu provedene su preliminarne sinteze kalijevih bakrovih(I) halidnih dvostrukih soli. Kalijeve bakrove(I) halidne dvostruke soli imaju raširenu primjenu u optoelektronici. Sinteze su provedene u vibracijskom kugličnom mlinu IST500. Dobiveni spojevi identificirani su difrakcijom na prahu te im je ispitana ionska provodnost.

Abstract (english)

Mechanochemical synthesis is synthesis induced by external mechanical energy, for example by grinding two or more substances in a solid state. Mechanical energy applied to a solid causes strong bonds to break, allowing new bonds to form. Mechanochemical synthesis enables synthesis without solvents or with a significantly reduced amount of solvents, making it a more environmentally friendly alternative to classical synthesis methods. In this paper, preliminary syntheses of potassium copper(I) halide double salts were carried out. Potassium copper(I) halide double salts are widely used in optoelectronics. The syntheses were carried out in a vibrating ball mill IST500. The obtained compounds were identified by powder diffraction and their ionic conductivity was tested.
