ABSTRACT: A series of glass sealants for solid oxide fuel cell (SOFC) with compositions SrO (x wt %) La2O3 (15 wt %) Al2O3 (15 wt %) B2O3 (40-x wt %) SiO2 (30 wt %) [x = 10, 15, 20, 25 & 30] [SLABS] ...
ABSTRACT: In this research paper we are reporting synthesis, structural and optical investigations of barium strontium titanate borosilicate glasses with addition of La2O3. Glasses were synthesized by ...
This study demonstrates the production of stoichiometrically controlled alkali-aluminosilicate gels ('geopolymers') via alkali-activation of high-purity synthetic amorphous aluminosilicate powders.
This paper is focused on the effect of the molar ratio of SiO2/Al2O3 on the microstructure and structure of the internal aluminium-silicon-oxide lattice of the glass-ceramic materials from the ...
The effect of pressure and temperature on the structure of silicate melts coexisting with silica-saturated aqueous electrolyte fluids enriched in fluorine or chlorine in the Na2O-Al2O3-SiO2-H2O system ...
The structural behavior of Al3+ in peralkaline glasses and melts along the Na2Si3O7-Na-2(NaAl)(3)O-7 join has been examined to 1200degreesC at ambient pressure with Si-29 MAS NMR and Raman ...
The dissolution of alumina in CaO-SiO2-Al2O3 slags is a critical phenomenon in metallurgical processes, notably in steel refining and continuous casting. This process is governed predominantly by mass ...
Abstract: In this study, we investigate the deposition of high-k dielectric materials, namely Al2O3 and HfO2, using atomic layer deposition for 4H-SiC metal-oxide-semiconductor applications. C-V ...
