Sodium silicate and hexametaphosphate promote the release of (oxyhydr)oxide nanoparticles from corroding iron [PDF]

open access: yes, 2022
Sequestrants such as polyphosphate and sodium silicate are used widely to control iron precipitation in drinking water, but less is known about their impacts on iron corrosion scale.

SBA-15 synthesis from sodium silicate prepared with sand and sodium hydroxide

open access: yesMaterials Research Express, 2020
In the industry, sodium carbonate is used to prepare sodium silicate; however, this process generates great volumes of CO _2 . In this work, sodium hydroxide has been proposed to prepare sodium silicate using natural sand. Two experimental variables were

Density of some titanium-bearing silicate liquids and the compositional dependence of the partial molar volume of TiO2 [PDF]

open access: yes, 1992
The densities of thirteen silicate liquids along the Na2SiO3-TiO2 and CaSiO3-TiO2 joins and six other titanium-bearing silicate liquids of the general formula TiSiO5 (where X = Li, Na, K, Rb, Cs, Ca, Sr, Ba) have been measured in equilibrium with air ...

Effects of structural relaxation on cationic tracer diffusion in silicate melts [PDF]

open access: yes, 1989
The glass transition in silicate melts is a curve in time-temperature space marking the transition of the melt structure from an unrelaxed, disequilibrium glass to a relaxed, equilibrium liquid. Tracer diffusivity data obtained in glasses vs.

Lime-Covered Soil Stabilization on the Surronding Area of a Lime-kiln (Torbat-Heydarieh) Using Sulfur and Sodium Silicate [PDF]

open access: yesپژوهش‌های آبخیزداری, 2021
Carbonates contaminate soil and water resources. The use of stabilizers is an effective method to improve soil characteristics. The single and interaction effects of two treatments consisting of sodium-silicate and sulfur at 0, 5, 10, and 15 g/m2 were ...

Application of Sodium Silicate Enhances Cucumber Resistance to Fusarium Wilt and Alters Soil Microbial Communities

open access: yesFrontiers in Plant Science, 2018
Exogenous silicates can enhance plant resistance to pathogens and change soil microbial communities. However, the relationship between changes in soil microbial communities and enhanced plant resistance remains unclear.

Use of rice husk ash to produce alternative sodium silicate for geopolymerization reactions [PDF]

open access: yesCerâmica, 2021
This study investigated the feasibility of synthesizing sodium silicate from rice husk ash (RHA) and its application to produce geopolymers. Samples were prepared at different SiO2/Al2O3 molar ratios (3.0, 3.5, and 4.0) for both sodium silicates ...

Compatibility studies of N-A-S-H and C-A-S-H Gels in Alkali-Activated Geopolymer Mortar [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering
The primary reaction products in the alkali-activated green tuff alumino-silicate geopolymer mortar are Natrium (sodium) Aluminum-Silicate Hydrate (N-A-S-H) and Calcium Aluminum-Silicate Hydrate (C-A-S-H) gels.
