Effect of iron oxide content on the crystallisation of a diopside glass–ceramic glaze

چکیده
The effect of iron oxide content on the crystallisation of a diopside glass–ceramic glaze was investigated using a glass–ceramic frit in the K2O–ZnO–MgO–CaO–Al2O3–SiO2 system and a granite waste glass. Measurements by X-ray diffraction (XRD) combined with scanning electron microscopy (SEM) and EDX microanalysis showed that the distribution of Fe ions among different crystalline phases such as franklinite (ZnFe2O4) and hematite Fe2O3 depends on the iron content in the original diopside mixture. Thus, the original glaze crystallises to franklinite or hematatite when iron content is greater than 2 and 15%, respectively. Author

Sinter-crystallisation in the diopside–albite system Part I. Formation of induced crystallisation porosity
The sinter-crystallisation was investigated in three model glasses (G1, G2 and G3) belonging to the diopside–albite system and forming between 30 and 60% diopside, respectively. The effect of bulk crystallisation on the sintering was studied by the addition of 0.7 wt.% Cr2O3 as nucleating agent to the G2 glass. The degree of sintering was evaluated by the variation of the apparent density while...

Apatite-wollastonite (A-W)-phlogopite glass-ceramic is considered to be difficult to resorb, but often, it has been incorporated in particulate form to create new bioactive composites for potential maxillofacial applications. With various compositions, the present work has attempted to prepare apatite-wollastonite (A-W)-phlogopite glass ceramic composites, by applying sintering. Here, three-poi...

The effect of titanium dioxide addition on bonding strength of CaO-P2O5 -Na 2O-TiO2glass-ceramic system was investigated as a coating on titanium substrate. Thus, different amounts of TiO2 (2, 3.5 and 5mol %) were added to the base glass batch composition. The prepared glaze slips were applied on the substrate by dip coating method, dried and then heat treated at various temperatures. After tha...

Electrode material for low-temperature co-fired diopside glass-ceramic used for microwave dielectrics was investigated in the present work. Diffusion of silver from the electrode to diopside glass-ceramics degrades the performance of the microwave dielectrics. Two approaches were adopted to resolve the problem of silver diffusion. Firstly, silicon-oxide (SiO₂) powder was employed and secondly c...
