The glass powder with a relatively complicated composition of 64.02SiO2–10.05B2O3–7.84Na2O–14.07ZnO–4.02Al2O3 (in wt.%) was first synthesized via sol–gel route. The optimal synthesis conditions for the amorphous gel are obtained. The glass transition temperature [Formula: see text] of xerogel was detected as 552[Formula: see text]C and the glass network structure formed by the [SiO4], [BO4] and [AlO4] units were confirmed by the Fourier Transform-Infrared Spectroscopy (FT-IR). The phase structure and morphologies of glass powder were characterized by X-ray diffractometer (XRD) and Field Emission-Scanning Electron Microscope (FE-SEM), the xerogels and sol–gel glasses exhibit amorphous phase when the heat-treatment temperature increases from [Formula: see text]C to [Formula: see text]C. The prepared glass powder with high specific surface areas and a large amount of pores contribute to the synthesis of a composite of glass-mullite-[Formula: see text]-eucryptite at a relatively low sintering temperature of [Formula: see text]C, which present a relatively low coefficient of thermal expansion (CTE) and high mechanical strength.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
