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

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.

Orta frekans indüksiyon yöntemi ile nano-metal ve nano-metal oksit partikül sentezinin incelenmesi

Synthesis of Ag, Fe2O 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.
