Development of sodium silicate adhesives for electrical steel bonding
… The aim of this project was to characterize sodium silicates as adhesives for such applications and develop methodology for their processing. The chemical and physical properties of the water-soluble sodium silicates were easily altered by changing the composition of Na₂O, SiO₄, and water, …

A Study of the flow Performance of a Sodium Silicate Furnace
The flow characteristics of neutral sodium silicate glass in an open hearth regenerative furnace have been studied using a one tenth scale physical model. The constraints of similarity have been investigated and discussed, and the use of sodium liquor as a cold modelling solution has been …

Bonding Characteristics and Devitrification Behavior in Iron-Containing Sodium-Silicate Glasses
… the addition of iron oxides to the sodium silicate glasses can strengthen the chemical bondings and immobilize the transport of sodium cations. Hence, they stabilize the binary sodium-silicate glasses and promote the formation of (gamma)-Na(,2)Si(,2)O(,5) phase. From a simple …

Investigating the use of sodium silicate to improve the flotation performance of Platreef and UG2 PGE ores
… which subsequently liberates the very fine phyllosilicate gangue minerals; namely serpentine and talc. The presence of these minerals poses three major problems to valuable mineral recovery. Firstly, serpentine slimes may form a hydrophilic layer on the valuable mineral surface leading to a …

Influence of sand friction angle, grout stiffness, and confinement on the behavior of acrylamide and sodium silicate grouted sand
In the geotechnical engineering field, grouting is a commonly used option within the plethora of ground improvement methods. Yet, the practice of grouting relies heavily on empirically developed models to estimate strength and predict grouted soil behavior. Collectively, these models consider many …

A Thesis on the Interactions between Lead Pipe Scales and Dissolved Silica from the Addition of Sodium Silicate as a Corrosion Inhibitor
… pathways for human exposure to lead. Addition of sodium silicate can potentially control lead release from lead service lines (LSLs) to the water that they convey, but the mechanism of silica uptake and corrosion control have not been reported. Knowledge of variables which affect the uptake of …

The development of a plastic refractory
… kyanite a refractory clay of high plasticity and sodium silicate as an air setting ingredient. Using 35 mesh calcined kyanite, 35 mesh raw kyanite, 100 mesh raw kyanite, 20 mesh A-l Sagger Mix refractory clay and sodium silicate, a plastic refractory was developed within certain statistical limits

The utilization of paper mill wastes in the flotation of manganese ores
… the amounts of tallol, pine oil, frother, sodium silicate silica depressor, and the hydrogen ion concentration was varied with either sulphuric acid or hydrated lime. Crude oleic acid from tallol was also tested as a collecting agent for the manganese dioxide in the ore, with auxiliary …

The Fate of Flame Volatized Sodium During the Combustion of Pulverized Coal in Reaction With Silica and Sulfur (Studied with the Aid of a Synthetic Coal)
<p>The interaction of flame volatilized sodium with sulfur and silica (quartz) was studied under coal fired boiler conditions in a laminar flow reactor. Measured compositions of sodium, sulfur and quartz were bound together in a synthetic coal matrix and subject to various temperature profiles …

Role of Water Chemistry in Lead Release during Drinking Water Supply and Augmentation
… lowered with the help of corrosion inhibitors. Sodium silicate is one such corrosion inhibitor and in typical deployments its addition results in an increase in the pH of water that can lower the solubility of lead corrosion products in addition to an increase in dissolved silicate. However, the …

The design of an experiment to investigate the fluidity of aluminum silicon alloys in carbon dioxide cured molds
… clay-free, silica sand with an organic liquid sodium silicate binder, then ramming this mix into molds or core boxes and injecting CO₂ gas. The CO₂ gas reacts with the sodium silicate binder forming a silica gel which hardens rapidly in atmospheric conditions. The CO₂ molds are more resistant …

Mechanics of seed-grown planar chemical gardens
… chloride into an aqueous solution of potassium silicate. He noted the formation of some strange, plant-like structures, which he recorded in his 1646 book Furni Novi Philosophici as "philosophical trees". Glauber would not have guessed that, three centuries later, his discovery opened up a whole …
