diopside (CaO·MgO·2SiO2) and wollastonite (CaO·SiO2) glass-ceramics, forming ∼60% crystal phase and ∼40% albite-like Na2O·Al2O3·6SiO2) residual glass were studied. Two other diopside glass-ceramics with higher Na2O and Al2O3 content were also investigated. The phase formation was estimated by DTA, XRD and pycnometry, while the densification process was evaluated by porosity variations, ilatomet...

Fluorescence microscopy-based affinity assay could enable highly sensitive and selective detection of airborne asbestos, an inorganic environmental pollutant that can cause mesothelioma and lung cancer. We have selected an Escherichia coli histone-like nucleoid structuring protein, H-NS, as a promising candidate for an amphibole asbestos bioprobe. H-NS has high affinity to amphibole asbestos, b...

In this study, the effect of wollastonite on mechanical, physical, and morphological properties composites made sesame stem (Sesamum indicum L.) gypsum was investigated. The mixing ratio as a lignocellulosic material with at three levels (10:90, 20:80, 30:70) (0%, 5%, 10%, based dry weight cement) were considered variables. Fire resistance (weight loss) tested according to ISO 11925-3 DIN EN 63...

During peritectic steel continuous casting, mold flux properties and film structures play significant roles in controlling slab quality. In this study, fluxes films for casting were obtained using mineral raw materials such as quartz, wollastonite, fluorite, soda ash others. The effects of on investigated through the measurement melting point, viscosity, crystallization temperature, critical co...

The solubility of andradite garnet was determined at 800 °C and 10 kbar in a solution of 10 mol% NaCl and 90 mol% H2O. Experiments were syntheses carried out with high-purity natural wollastonite, reagent hematite or natural specular hematite containing ~1 wt% TiO2, and fluid. All experiments were performed with Mn2O3-Mn3O4 or Fe2O3-Fe3O4 oxygen buffers in a piston-cylinder apparatus with NaCl ...

The weathering of silicate minerals removes carbon dioxide (CO2) from the atmosphere over geologic timescales and is also investigated as an engineered strategy to mitigate climate change on decadal timescales. “Enhanced rock weathering” (ERW) a removal that involves spreading pulverized, highly reactive at Earth's surface such within agricultural natural soils. rate efficacy ERW in soils remov...
