Abstract

Preparation of nanosized SnO2 electroceramic powders via hydrothermal synthesis was investigated as a function of initial concentration and treatment time in order to understand the formation and growth mechanisms. SnO2 powder was successfully synthesized from the hydrous tin oxide by hydrothermal synthesis at 200°C. Crystalline SnO2 particles with a specific surface area as high as 170 m2/g were produced in a single step without requiring any calcination process. As initial concentration of metal cation increases from 0.0125 to 0.05 M, an Ostwald ripening type growth process was observed in the crystallite size from 3.1 to 4.6 nm. Evolution of tin oxide particles was also investigated by altering the treatment time from 1 to 24 h and a diffusion controlled growth behavior was observed as a function of synthesis time.

Özet

Nano boyutlu SnO2elektroseramik tozların hidrotermal yöntemle üretimi, tozların oluşum mekanizmasını anlamak üzere başlangıç derişimi ve işlem süresinin bir fonksiyonu olarak incelendi. SnO tozları hidrotermal yöntemle su içeren kalay oksitten 2000C de başarıyla sentezlendi. 170 m2/g a kadar spesifik yüzey alanınasahip kristal SnO2 tozları kalsinasyon gerektirmeden tek basamakta üretildi. Başlangıç metal katyon derişimi 0.0125 den 0.05 M a çıkarıldığında Ostwald irileşmesi türünde bir büyüme süreciyle kristalit boyutunun 3.1 den 4.6 nm ye çıktığı gözlendi. Kalay oksit partiküllerinin oluşumu 1 ile 24 saat aralığında değiştirilerek incelendi ve sentez süresinin bir fonksiyonu olarak difüzyon kontrollü büyüme davranışı tespit edildi
