“…The precursor concentration had again a significant effect on the titanium dioxide particles. Particle sizes became coarse by increasing solution concentration, which was typical for the nanoparticle production via aerosol based methods [24]. XRD study of generated TiO2 particles revealed the pure TiO2 formation with an anatase structure.…”

“…For this reason, production of nanoparticles with controlled morphology and size distribution is very critical to meet the demand of required function. So far, many techniques have been developed to synthesize metal and metal oxide nanoparticles with uniform form and proportion including; laser ablation [3], RF thermal plasmas [4], flame synthesize [5], sol-gel [6], chemical vapor synthesis (CVS) [7], mechanical attrition [8] and spray pyrolysis [9], and etc.…”

“…Although this is one of the most common demands of titanium dioxide, interest for other implementations has increased tremendously; especially in waste water treatment, air purification, selfcleaning paints and solar cells [20][21][22][23]. The previous studies on the titanium oxide particles produced by different spray pyrolysis given in Table 2 [24][25][26][27] revealed that the concentration of the precursor is the most effective parameters on the titanium oxide particles production via spray pyrolysis and the average size of the powders are tuneable easily via altering the concentration of the precursors. 100-500 Moravec et al [26] 100-400 Tetra-n-butyl orthotitanate (C16H36O4Ti) -800 Bogovic, et al [27] Iron oxide nanoparticles are currently in the use of vitro diagnostics for decades due to their biocompatible properties.…”

“…Besides, the manufacturing of nano particles with these types of techniques from all soluble or organometallic compounds is relatively easier and suitable for implementing mass production compared to the other developed methods; suggested previously [3][4][5][6][7][8][9]. Considering the fact that, we had rather to use an aerosolbased production technique in the synthesis of nano particles.…”

Synthesis of Ag, Fe2O3 and TiO2 was investigated in medium frequency induction system to determine ideal conditions for the particle production with desired size. A high frequency ultrasonic generator was attached to induction furnace to synthesize particles from solutions of AgNO3, FeCl3, titanium tetra iso-propoxide (TTIP). Experiments were carried out under concentrations of 0.1 M, 0.01 M at constant parameters; 15 min. time, 800 ºC temperature, 1.0 L/min. flow rate. X-ray diffraction (XRD) studies confirmed the particle formation without contamination. Scanning electron microscopy (SEM) examinations revealed that size of particles were in the range of 50 nm to 400 nm.Keywords: nanoparticle, titanium dioxide, iron oxide, silver, medium frequency induction Orta frekans indüksiyon yöntemi ile nano-metal ve nano-metal oksit partikül sentezinin incelenmesi ÖZ Bu çalışmada, gümüş (Ag), demir oksit (Fe2O3) ve titanyum dioksit (TiO2) partiküllerinin nano-boyutta üretimleri için gerekli şartlar, orta frekanslı indüksiyon partikül üretim sisteminde incelenmiştir. Partikül üretim sistemi; orta frekanslı indüksiyon fırını ile yüksek frekans ultrasonik atomizerin birleştirilmesi ile oluşturulmuştur. Bahsi geçen nanopartiküllerin üretimi 0,1 M ve 0,01 M konsantrasyonların da AgNO3, FeCl3.6H2O, Titanyum tetra izopropoksit (TTIP) başlangıç malzemeleri kullanılarak gerçekleştirilmiştir. Deneyler, sabit 800 ºC reaksiyon sıcaklığı, 1.0 L/dk. taşıyıcı gaz debisi ve 15 dk. deney süresi şartlarında yapılmıştır. XRD ve SEM kullanılarak karakterize edilen nanopartiküllerin safsızlık içermediği ve 50 nm ile 400 nm arasında değişen boyutlarda oldukları görülmüştür.

“…Generally, a onedroplet-to-one-product particle (ODOP) conversion is considered the typical particle formation mechanism in conventional spray pyrolysis (CSP). In this project, various modified spray pyrolysis methods were developed and introduced for nanoparticle synthesis, including salt-assisted spray pyrolysis (SASP) [9][10][11][12] and low pressure spray pyrolysis (LPSP) [13][14][15][16][17][18] as well as flame-assisted spray pyrolysis (FASP). [19][20] Salt-assisted spray pyrolysis (SASP) is a modified spray pyrolysis method that introduces salts into the precursor solution.…”
