Li 2 O-Al 2 O 3 -SiO 2 -NiO cam-seramiğinin üretimi ve karakterizasyonu

Bu çalışmada, Li 2 O-Al 2 O 3 -SiO 2 -NiO cam-seramik numunesi geleneksel yöntem kullanılarak üretildi ve X-ışınıkırınımı (XRD) analizi, Fourier dönüşümlü kızılötesi (FTIR) spektroskopisi, diferansiyel termal analiz (DTA),termogravimetrik analiz (TGA) ve taramalı elektron mikroskopisi (SEM) teknikleri kullanılarak karakterizeedildi. Numunenin iki fazlı çok kristalli bir yapıya sahip olduğu görüldü. Si-O-Si ve Si-O-Al bağlarının titreşimmodlarına ait bantlar FTIR spektrumunda gözlendi. Üretilen numunenin oda sıcaklığı ile 1000 °C aralığındatermal davranışı araştırıldı. Numunenin morfolojisi incelendi ve numune içerisinde bir safsızlık tespit edilmedi.

Production and characterization of Li 2 O-Al 2 O 3 -SiO 2 -NiO glass- ceramic

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.
