Mineralleştirici ilavesinin Vanadyum-zirkon seramik pigment özelliklerine etkisinin incelenmesi

Abstract

Bu çalışmada, V-zirkon seramik pigmentinin katı-hal sentez yöntemiyle üretiminde mineralleştirici (NaF) kullanımının pigmentlerin rengi ve sentezleme koşullarına etkisi araştırılmıştır. Bu amaçla ZrO2, SiO2 ve V2O5 başlangıç kompozisyonu ile NaF ilaveli ve ilavesiz hazırlanan karışımlar 750-1050 C sıcaklıklarda kalsine edilerek V-zirkon pigmentlerin üretimi gerçekleştirilmiştir. Üretilen pigmentlerin faz analizi, morfolojik özellikleri ve L*a*b* renk ölçümleri sırasıyla XRD, FE-SEM ve UV-Vis-spektra analizleri ile karakterize edilmiştir. Elde edilen sonuçlardan, mineralleştirici kullanımının pigment faz dönüşümlerinin daha düşük sıcaklıkta gerçekleşmesine ve kararlı mavi renk oluşumuna katkı sağladığı görülmüştür.

Investigation of the Effect of Mineralizer Addition on Vanadium-Zircon Ceramic Pigment Properties

Abstract

In this study, the effect of mineralizer (NaF) on pigment colours and synthesis conditions in the production of V-zircon pigment by solid-state synthesis method was investigated. For this purpose, the initial composition of ZrO2, SiO2 and V2O5 mixtures prepared with and without NaF addition were calcined at temperatures of 750-1050 C and the production of V-zircon pigments was carried out. Phase analysis, morphological properties and L*a*b* colour measurements of the pigments were characterized by XRD, FE-SEM and UV-Vis-spectra analysis, respectively. From these results, it was observed that the use of mineralizers contributes to the fact that pigment phase transformations occur at a lower temperature and the formation of a stable blue colour.
