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 ...
متن کاملTHE 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...
متن کاملEFFECT 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...
متن کاملCorrelation between the activation enthalpy and Kohlrausch exponent for ionic conductivity in oxide glasses.
We have established for alkali ions in oxide glasses a strong correlation between the fractional (Kohlrausch) exponent β in the conductivity relaxation function, exp[-(t/τ*)β], and the activation energy E*a of τ* and σ when varying the composition of oxide glass formers and the alkali ions while holding the alkali-ion concentration constant. An even stronger correlation of the trends in β and t...
متن کاملEffective role of CaO/P2O5 ratio on SiO2-CaO-P2O5 glass system
In the present work, the effect of the CaO/P2O5 ratio on the composition of sol-gel synthesized 58SiO2-(19 - x)P2O5-(23 + x)CaO (x = 0, 5, 10 and 15 mol%) glass samples was studied. Further, the effect of NBO/BO ratio on hydroxy carbonated apatite layer (HCA) forming ability based on dissolution behavior in simulated body fluid (SBF) solution was also investigated. CaO/P2O5 ratios of synthesize...
