Glass-ceramic enamels derived from the Li2O-Na2O-Al2O3-TiO2-SiO2 system

Microstructure and Properties of Li2O-Al2O3-SiO2-P2O5 Glass-Ceramics

Serials Li2O–Al2O3–SiO2 matrix glasses and glass-ceramics with different content of P2O5 were prepared by conventional melt cooling method and crystallization process. The effects of P2O5 content on microstructure and properties such as viscosity, melting temperature and coefficient of thermal expansion (CTE) of Li2O–Al2O3–SiO2–P2O5 glasses and glass-ceramics were investigated by DSC, XRD, CTE ...

Glass-Ceramic Material from the SiO2-Al2O3-CaO System Using Sugar-Cane Bagasse Ash (SCBA)

THE EFFECT OF COMPLEX NUCLEATING AGENT ON THE PHYSICAL AND CHEMICAL PROPERTIES OF Li2O-Al2O3-SiO2 GLASS CERAMIC

Abstract: In the present work, effect of the nucleating agent such as TiO2, ZrO2, P2O5, Ye2O3 and CeO2 in single, double, triple and fourth systems on the crystallization behavior of various compositions was studied. Using differential thermal analysis (DTA), the composition of Li2O-Al2O3-SiO2 (LAS) was optimized and the coefficient of thermal expansion (CTE), three point flexural strength, har...

Characterizing the residual glass in a MgO/Al2O3/SiO2/ZrO2/Y2O3 glass-ceramic

The non-isochemical crystallization of glasses leads to glass-ceramics in which the chemical composition of the amorphous matrix differs from that of the parent glass. It is challenging to solely analyse the properties of these residual glassy phases because they frequently contain finely dispersed crystals. In this study, the composition of the residual glass matrix after the crystallization o...

EFFECT OF TiO2 ADDITION ON BONDING STRENGTH OF CaO-P2O5 Na2O-TiO2 BIOACTIVE GLASS CERAMIC COATING

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...
