Silicates characterization as potential bacteriocin-carriers
Two different silicates, zeosil and expanded perlite, were characterized as potential carriers of a bacteriocin with anti-Listeria monocytogenes activity, produced by Enterococcus faecium CRL1385. Specific surface areas ...
Nano lithium silicates as flame-retardant impregnants for Pinus radiata
(Sage Publications Ltd, 2011-09)
Aqueous solutions of nano lithium silicates with 5.5/1.0 and 7.5/1.0 silica/alkali molar ratios were used to impregnate Pinus radiata. To obtain these impregnants, a solution of 3.5/1.0 SiO2/Li2O molar ratio was used; this ...
Silicate Ions as Corrosion Inhibitors for Carbon Steel in Chloride-Contaminated Concrete Pore Simulating Solutions
(NACE International, 2020-10)
Silicate ions were tested as corrosion inhibitors for construction steel using concrete pore simulating solutions contaminated with chloride ions. The results are compared to those from solutions with no silicate and with ...
Reactivity of rice husk-derived lithium silicates followed by in situ Raman spectroscopy
(Elsevier Science Sa, 2019-03)
Lithium silicates were synthesized using rice husk ash as a precursor of silica to be used in CO2 capture. Two different treatment steps, with water (SiO2-W) or HCl 3 M (SiO2-A), were carried out prior to the rice husk ...
Environmentally friendly, nano lithium silicate anticorrosive coatings
(Elsevier Science Sa, 2012-02)
The aim of this study was to develop environmentally friendly, nano-structured inorganic coatings suitable for the protection of metal substrates. The formulation variables included (i) two binders based on lithium silicate ...
