Abstract

Hekzagonal bor nitrür (hBN) numuneleri, 1373 K'de farklı metal karboniller, M (CO)6, (M = Mo, Cr, W) ile modifiye edilmiş O’Connor yöntemi kullanılarak hazırlandı. Numuneler FTIR, XRD ve SEM teknikleri ile karakterize edildi. XRD sonuçları, katmanlar arası aralıkta bir artış olduğunu gösterdi ve 1373 K'de nano ölçekli ürünlerin oluşumu gözlendi. Hesaplanan kafes değerleri hBN için bildirilen değere çok yakındı ve Debye-Scherrer denklemine göre ürünlerin tane büyüklüğünün nano ölçekte olduğu bulundu.

Keywords
