Alüminyum Üretim Teknolojilerindeki Gelişmeler, Çevreye Etkisi ve Uygulama Alanları

Alüminyum yaşantımızın pek çok alanında kullandığımız cazip özellikleri sebebi ile vazgeçilmez bir malzemedir. Bu çalışmada alüminyumun özellikleri, sektördeki yeri, üretim teknolojisi, üretimdeki enerji ihtiyacı, çevreye etkisi ve tarihsel serüveni ana hatları ile incelenmektedir. Alüminyumun dünya kabuğunun %8’ini oluşturan boksit minerali halinde doğadan alınmaktadır. Kullanılmakta olan ve geliştirilen yeni yöntemler ile tüketiciye hem ekonomik fırsatlar hem de geniş bir ürün yelpazesi sunulmaktadır. Bu özelliklerine ek olarak düşük yoğunluk, iletkenlik, işlenebilirlik gibi konularda sunduğu avantajlarda bu mineralin önemini artırmaktadır. Ekonomik Kalkınma ve İşbirliği Örgütü (OECD) ülkelerindeki 33 kg/kişi.yıl tüketim miktarına oranla düşük olan Türkiye alüminyum üretimi son yıllardaki farkındalık ile yıllık kişi başına 10 kg sınırını zorlamaktadır.

Developments in Aluminum Production Technologies, Environmental Impact and Application Areas

Aluminum is an indispensable material due to its attractive properties that we use in many areas of our life. In this study, the properties of aluminum, its place in the industry, production technology, energy need in production, its impact on the environment and its historical adventure are discussed. Aluminum is taken from nature as a bauxite mineral, which accounts for 8% of the world's crust. It offers the consumer both economic opportunities and a wide range of products with new methods that are being used and developed. In addition to these features, it has advantages such as low density, conductivity and processability, which increase the importance of this mineral. In the Organisation for Economic Co-operation and Development (OECD) countries aluminum consumption is 33 kg/person.year compared to that of Turkey (approximately 10 kg/person.year) consumption of aluminum with low awareness in Turkey.
