Li2O-Al2O3-SiO2-NiO cam-seramiğinin üretimi ve karakterizasyonu

Abstract

Bu çalışmada, Li₂O-Al₂O₃-SiO₂-NiO cam-seramik numunesi geleneksel yöntem kullanılarak üretildi ve X-ışını kırınımı (XRD) analizi, Fourier dönüşümlü kızılötesi (FTIR) spektroskopisi, diferansiyel termal analiz (DTA), termogravimetrik analiz (TGA) ve taramalı elektron mikroskopisi teknikleri kullanılarak karakterize edildi. Numunenin iki fazlı çok kristalli bir yapıya sahip olduğu görüldü. Fonksiyonel gruplar tespit edildi. Üretilen numunenin oda sıcaklığı ile 1000 °C aralığında termal davranışı araştırıldı. Numunenin morfolojisi incelendi ve numune içerisinde herhangi bir safsızlık tespit edilemedi.

Production and characterization of Li2O-Al2O3-SiO2-NiO glassceramic

Abstract

In this study, a Li2O-Al2O3-SiO2-NiO glass-ceramic sample was produced using the conventional method and it was characterized by X-ray diffraction (XRD) analysis, Fourier transform infrared (FTIR) spectroscopy, differential thermal analysis (DTA), thermogravimetric analysis (TGA) and scanning electron microscopy (SEM) techniques. It was seen that the sample has the biphasic polycrystalline structure. The bands belonging to the vibration modes of Si-O-Si ve Si-O-Al bonds were observed in the FTIR spectrum. The thermal behavior of the as-produced sample was investigated in the range of room temperature to 1000 °C. The morphology of the sample was investigated and no impurity in the sample was detected.
