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 ...
Fire retardant impregnants for woods based on alkaline silicates
(Elsevier, 2008-12-02)
The aim of this paper was to determine the fire performance of wood panels (Araucaria angustifolia) impregnated in a pressure vessel with post-cured alkaline silicates (water glasses). Several commercial silicates based ...
Ytterbium oxide as radiopacifier of calcium silicate-based cements. Physicochemical and biological properties
(2018-09-01)
This study evaluated physicochemical properties, cytotoxicity and bioactivity of MTA Angelus (MTA), calcium silicate-based cement (CSC) and CSC with 30% Ytterbium oxide (CSC/Yb 2 O 3 ). Setting time was evaluated using ...
Calcium Silicate-based experimental sealers: Physicochemical properties evaluation
(2021-01-01)
The aim of this study was to evaluate physicochemical properties of calcium silicate-based experimental (CS) endodontic sealers, developed using two different vehicles: polyethylene glycol (PG) (CS-PG) or polyethylene ...
Evaluation of Physicochemical Properties of a New Calcium Silicate–based Sealer, Bio-C Sealer
(2019-01-01)
Introduction: Calcium silicate–based materials have been proposed as root canal sealers for root canal treatment. The aim of this study was to evaluate the physicochemical properties of a new calcium silicate–based sealer ...
Magmatic platinum nanoparticles in metasomatic silicate glasses and sulfides from Patagonian mantle xenoliths
(Springer Verlag, 2019)
Platinum-rich nanonuggets (s.l., nanoparticles) are commonly produced in experiments attempting to quantify the solubility or partitioning of noble metals in silicate and sulfide melts. However, it has been thought that ...
Effect of different radiopacifying agents on the physicochemical properties of white portland cement and white mineral trioxide aggregate
(2012-03-01)
Introduction: The aim of this study was to evaluate the pH, calcium ion release, setting time, and solubility of white mineral trioxide aggregate (WMTA) and white Portland cement (WPC) combined with the following radiopacifying ...
Physicochemical and biological properties of new tricalcium silicate-based repair material doped with fluoride ions and zirconium oxide as radiopacifier
(2022-04-01)
This study evaluated the physicochemical and biological properties of novel reparative materials composed of pure tricalcium silicate (Ca3SiO5), Ca3SiO5 doped with fluoride ions (Ca3SiO5-F) and their association with ZrO2 ...
Physicochemical, biological, and antibacterial evaluation of tricalcium silicate-based reparative cements with different radiopacifiers
(2021-02-01)
Objective: To evaluate tricalcium silicate-based (TCS) experimental materials, associated with zirconium oxide (ZrO2), calcium tungstate (CaWO4) or niobium oxide (Nb2O5) radiopacifiers, in comparison with MTA Repair HP ...
Different Sources of Silicon by Foliar Spraying on the Growth and Gas Exchange in Sorghum
(2019-12-01)
The efficiency of silicon (Si) foliar spraying in sorghum plants can be increased with new sources that may enhance the uptake of the beneficial element with reflexes in physiology. This study investigated the effect of ...
