Fire resistance of wood impregnated with soluble alkaline silicates
(Hindawi Publishing Corporation, 2007-12-02)
The aim of this paper is to determine the fire performance of wood panels (Araucaria angustifolia) impregnated with soluble alkaline silicates. Commercial silicates based on sodium and potassium with 2.5/1.0 and 3.0/1.0 ...
Silicates characterization as potential bacteriocin-carriers
(Elsevier, 2010-01)
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 ...
Fossilised geothermal surface features of the Whitianga Volcanic Centre (Miocene), Coromandel Volcanic Zone, New Zealand: Controls and characteristics
(Elsevier Science, 2019-09)
The Late Miocene Whitianga Volcanic Centre of the Coromandel Volcanic Zone, North Island, New Zealand, is host to 18 known, siliceous and intensely silicified deposits including: silicified volcanics; sediments of inferred ...
Ethyl silicates with different hydrolysis degree like non-flammable impregnating material for woodSilicatos de etilo con diferente grado de hidrólisis como material impregnante ignífugo para maderas
(Universidad del Bío-Bío, 2008-02)
La madera, al igual que el resto de los materiales, no puede resistir indefinidamente la acción del fuego sin sufrir deterioro. En este trabajo se estudió el comportamiento de paneles de madera de baja densidad impregnadas ...
Influence of the porosity caused by incomplete sintering on the mechanical behaviour of lanthanum silicate oxyapatite
(Elsevier, 2018-08)
Lanthanum silicate oxyapatite (LSO) is an encouraging material for its use as an electrolyte in intermediate temperature solid oxide fuel cells. There is a vacancy in knowledge respecting to LSO's mechanical properties, ...
Sintesis de heterociclos mediante nanoparticulas de silice mesoporosa modificadas con acido tungstoforico
(Asociación Química Argentina, 2019-01)
Los heterociclos están presentes en la mayoría de productos naturales bioactivos y drogas sintéticas, entre otras. Las aminas heterocíclicas son sustancias, muy comunes y tienen muchas propiedades biológicas importantes. ...
