Abstract

Copper powders, due to their superior physicochemical properties, are widely utilized in various technological applications such as the production of sintered bronze brake pads, sintered components through blending with iron powders, and applications requiring thermal conductivity. As such, copper powder is considered a significant industrial material with a broad range of applications. Ongoing research continues to expand its utility and offers innovative applications across diverse industries. While literature primarily reports electrolytic methods for copper powder production, this study presents the fabrication of commercial copper powders using a vertical gas atomization system equipped with a closely coupled supersonic nozzle. In the experimental production conducted via vertical gas atomization, copper melting at 1350°C was atomized under a nitrogen gas pressure of 35 bar, which was determined based on the fluid viscosity of the molten metal. X-ray diffraction (XRD) analysis was employed to determine the phase composition of the produced copper powders. Particle size distribution analysis was also performed. In addition, scanning electron microscopy (SEM) was used to evaluate the particle shape and morphology of the commercial copper powders. Production was deemed successful, with the majority of particles exhibiting near-spherical morphology and sizes predominantly around 100 microns. In addition, image analysis techniques for particle morphology were used, and the results were examined comparatively with particle size distribution data.

Özet

Bakır tozları yüksek fiziko-kimyasal özellikleri sayesinde sinter bronz fren balata üretimi, demir tozu ile karıştırılarak sinter parça üretimi, termal iletken uygulamaları gibi birçok teknolojik alanda kullanılmaktadır. Dolayısıyla bakır tozları, geniş bir kullanım alanına sahip önemli bir endüstriyel malzemedir. Sürekli yapılan araştırmalarla, bu tozların kullanım alanı genişlemekte ve endüstriye yeni ve yenilikçi uygulamalar sunmaktadır. Literatürde bakır tozlarının üretimi için çoğunlukla elektroliz yöntemi kullanılırken, bu çalışmada düşey gaz atomizasyon ve yakından eşlemeli süpersonik nozul sistemi kullanılarak, ticari bakır tozlarının üretimi gerçekleştirilmiştir. Düşey gaz atomizasyon ünitesi ile yapılan bakır tozu üretimi çalışmasında, eriyik sıvı metal sıcaklığı akışkan vizkozitesi için 1350°C ve atomizasyon basıncı olarak azot gazı ile 35 bar basınç altında toz üretimi gerçekleştirilmiştir. Bakır tozlarının faz tayinin belirlenmesi amacıyla XRD analizi uygulanmıştır. Üretimi gerçekleştirilen bakır tozlarının parçacık boyut analiz ölçüm işlemi gerçekleştirilmiştir. Ticari bakır tozlarının şekil ve morfolojik açıdan değerlendirilmesi amacıyla, taramalı elektron mikroskobu (SEM) ile mikro yapı görüntüleri elde edilmiştir. Bakır tozlarının üretimi başarılı ve çoğunluğunun 100 mikron civarı küresel şekil ve morfolojisinde ortaya çıktığı belirlenmiştir. Ayrıca parçacık morfolojisi için görüntü analiz teknikleri kullanılarak sonuçlar parçacık boyutu dağılım verileriyle karşılaştırmalı olarak incelenmiştir.
