Wastes management studies concerning slaker grits, a rich calcium carbonate landfilled residue from the pulp and paper industry, are focused on their application in construction field due to calcareous nature. To best of our knowledge, grits addition high content ceramic frit formulation behavior as glaze has not yet been explored, being aim this work. Grits were added oxide source 0, 50%, 100%...

A variety of artificial fibers extensively employed as lining in high-temperature apparatus may undergo a devitrification process that leads to significant changes in the chemical-physical properties of the materials. Among them, the crystallization of carcinogenic minerals, such as cristobalite, has already been documented for alumino-silicate ceramic fibers. Five fibrous samples with differen...

Nucleation and crystallization from xerogels of the system Si02-ZnOA1203 are induced and probed by Cr. Besides the traditional techniques, such as X-ray diffraction, SAXS and TEM, ESR and optical techniques especially laser spectroscopy are employed for the investigation of the structural evolution during thermal treatments of these xerogels. Cr is served not only as a structure probe but also ...

SiO2-TiO2 glasses produced by aerodynamic levitation coupled to laser heating or sol-gel spray-drying were compared highlight their structural differences. Glass formation was possible melt-quenching up 10 mol% TiO2, while higher contents led devitrification. Raman spectroscopy and solid-state 17O 29Si magic-angle-spinning nuclear magnetic resonance confirmed the clear emergence of Ti-O-Si bond...

Industrial oil and gas eruptions underwater have been found in the pyroclastic rocks of Huoshiling Formation continental lacustrine basin Changling fault depression, Songliao Basin. This paper investigates reservoir space characteristics, physical pore structure differences subaqueous reservoirs Formation, causes property different types their formation evolution processes are analyzed. (1) The...
