Abstract

In this paper we present the production of NiTi/Ni-TiO2 composite nanoparticles via the synthesis method called ultrasonic spray pyrolysis (USP). The precursor solution for the synthesis of spherical NiTi particles was prepared from an orthodontic wire with a chemical composition of Ni (amount fraction x = 51.46 %) and Ti (x = 48.54 %). TEM microscopy, in combination with EDX analyses, was used for a detailed characterization of the obtained NiTi nanoparticles. The results showed the nanoparticle sizes ranging from 60 nm to 600 nm, depending on the parameters of the production procedure. This showed the versatility of the new USP synthesis procedure, proving its usefulness for different materials and applications.

Secondary title: Sinteza kompozitnih nanodelcev NiTi/Ni-TiO[sub]2 z ultrazvočno razpršilno pirolizo
Secondary abstract: V tem prispevku je predstavljena izdelava NiTi/Ni-TiO2 kompozitnih nanodelcev po metodi ultrazvočne razpršilne pirolize (USP). Sferični nanodelci NiTi so bili izdelani iz ortodontske žice s kemijsko sestavo Ni (množinski delež x = 51,46 %) in Ti (x = 48,54 %). Za karakterizacijo nanodelcev je bila uporabljena TEM-mikroskopija v kombinaciji z EDX-analizo. Rezultati meritev so pokazali velikostno porazdelitev narejenih nanodelcev v razponu od 60 nm do 600 nm v odvisnosti od parametrov izdelave. To potrjuje vsestranskost novega izdelovalnega postopka USP in njegovo uporabnost za različne materiale in aplikacije.
