  Montmorillonite-rich clay soil stabilization with powdered sodium silicate and lime was reported, but the low solubility and migration of the lime in the pore liquid inhibited the application of this technique for in situ construction (Rafalko et al., , Sukmak et al., a, Phetchuay et al., ).Cited by: Sodium silicates serve a wide range of end use markets, including soaps and detergents, pulp and paper, paint and pigments, catalysts, and metal cleaning. 1. Chemical Identity Name: Sodium Silicate Chemical Abstracts Service (CAS) number: Sodium silicate is the generic name for a series of compounds derived from soluble sodium silicateFile Size: KB. In book: Silicon in Agriculture (pp) Soluble potassium or sodium silicates are completely water soluble and can be used as foliar fertilizers, but are usually too expensive for soil. Sodium Silicate powder is a water soluble silicate,generally assumed as a combination of alkali metal oxide, silica and water. It is a widely used basic chemical material. Some of it's uses are as under: * Soap industry * In detergent industry * This powder is used as anti-oil agentfilling agent and corrosion buffer.

Sodium silicate solution is obtained by chemical attack of silica sand with caustic soda through a two-steps reaction path, as per following reactions: 2NaOH → Na 2 O + H 2 O Na 2 O + nSiO 2 → Na 2 O*nSiO 2 n = ÷ Hybrid polyacrylate-silicate hydrogels were obtained in the presence of N,N′-methylenebisacrylamide (NNMBA) as the cross-linking monomer and sodium thiosulphate/potassium persulphate (NTS/KPS) as the redox initiators. The results of the tests allowed us to conclude that a hybrid structure with a polyacrylate scaffolding and a silicate matrix had been obtained.   Sodium silicate can also act as a flocculating agent or to increase the viscosity of a liquid mixture, as well as a component in some cements. Sodium silicate has the interesting property to decompose when treated with organic solvents such as ethanol and acetone. This results in formation of a resilient rubber-like gel, which is a form of.

Sodium silicate is added to fruit processing water to increase the density of the water, which allows 49 the pears to float (Willett et al., ). Pear floatation is used to prevent damage to the fruit during. Technical Evaluation Report Name of Material Crops or Livestock Ma Page 2 of instructions on taking soil and water samples for analysis. It also gives suggestions on how to reduce the harmful effects of salts and sodium, and tells you where to get advice in making reclamation and management decisions for each situation. Managing salt and sodium affected soils, together with waters used for irrigation, is complex. siliceous forms of sodium silicate because they are of a lower pH3. It is believed that these chemical properties make sodium silicate poten­ tially useful in soil stabilization, For example, the introduction of a small proportion of an acid or of an alkaline earth metal ion will pre­ cipitate an acqueous solution of sodium silicate and form.
