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 nano-partiküllerin üretimi 0,1 M ve 0,01 M konsantrasyonların da AgNO₃, FeCl_3.6H₂O_, 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 nano-partiküllerin safsızlık içermediği ve 50 nm ile 400 nm arasında değişen boyutlarda oldukları görülmüştür.

Investigation of nano metal and metal oxide particles synthesis by using medium frequency-induction method

Öz

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.
