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...

In this study, the contents of thirty-five elements (nine major-minor oxides, twenty-one heavy metals, and five other elements) in eighty-four muscovite samples collected from three commercially operated quarries Manisa province Turkey were determined using an energy dispersive X-ray fluorescence (EDXRF) spectrometer. The mean concentrations SiO2, Al2O3, K2O, MgO, Na2O, Fe2O3, P2O5, TiO2 CaO an...

This study was carried out at Federal Polytechnic; Ado Ekiti in state on geochemical appraisal of three different genetically derived lateritic soils from south western Nigeria and their respective engineering performance 2019. Twelve (12) disturbed soil samples were collected granite (GDS), gneiss (GNS) migmatite (MGS) rock terrains. These four horizons 0.5m intervals, resulting into a maximum...

The main problem affecting the life of refractory linings in furnaces is alkaline corrosion formed during biomass combustion, especially systems with SiO2–Al2O3. This effect very intensive compared to using conventional technologies designed for burning traditional fuels. study focuses on development a new type andalusite material higher resistance K2CO3 and fly ash after combustion. original l...

In this study, 10 mol% ZrO2 was added to a 27CaO-5P2O5-68SiO2 (mol%) base composition synthesized via a simple sol-gel method. This composition is similar to that of a frequently investigated bioactive gel-glass. The effects of ZrO2 on the in vitro bioactivity and MG-63 cell proliferation of the glass and its derivative polycrystalline (glass-ceramic) powder were investigated. The samples were ...
