dvr Sodium Silicate Water Glass

Sodium silicate, also called water glass or Soluble Glass, is any one of several compounds containing sodium oxide, Na2O, and silica, Si2O, or a mixture of sodium silicates varying ratios of SiO2 to Na2O, solids contents, and viscosity. Traditionally, sodium silicates are classified according to the acid from which they are derived as Orthosilicate Na4SiO4; Metasilicate Na2SiO3; Disilicate Na2Si2O5; Tetrasilicate Na2Si4O9. They are also classified by an X-ray diffraction method according to their crystalline structure. All these compounds are colorless, transparent, glasslike substance available commercially as a powder or as a transparent, viscous solution in water. They can be dissolved in water to form a syrupy liquid. Some forms are slightly soluble, and some are almost insoluble; they are best dissolved by heating with water under pressure. The solutions are strongly alkaline. They are produced chiefly by fusing sand and sodium carbonate in various proportions. The use of sodium silicates is as a raw material for making silica gel. Also used in detergent; as a cement for glass, pottery, and stoneware; for fireproofing paper, wood, cement, and other substances; for fixing pigments in paintings and cloth printing.

ANLYSIS PROCEDEURE OF SODIUM SILICATE : Take 5gm of sodium dilute it to 250ml in SMF with dist. Water , take 50 ml of the diluted solution add 2-4 drops of  methyl red indicator.  Then titrate it against IN {approx.}  HCL  Light Pink is the end point. Take this reading as %u201CA%u201D ml. To this solution add 5 gm of sodium fluoride dissolve properly add  6-7 drops of methyl red indicator titrate against IN HCL  appearance of slight pink colour is the end point . Take this reading as %u201CB%u201D ml

  • Botanic Potassium Thiocynate ;- dissolve 1.0gm of potassium thiocynate in10ml of water. Add sufficient n-butano to makeup to 100ml. Shake vigorously until the solution is clear.
  • Dilute H2SO4 :- approx.10% 
  • Standard Iron solution : weight 0.702gm of Ferrus Ammonium sulfate. Dissolve in 10ml dilute H2SO4 then make up 1000ml with water. Transfer 10 ml of this solution in 100ml M.Flask and make up 100ml with water. 1ml of this solution is equivalent to 0.01mg of iron 



  • Sample Reading: take about 5gm of the sample accurately weighted. Dissolve it in distilled water and make the solution exactly 100ml. Take 10 ml of this solution add 1ml concentrated Nitric acid. Boil the solution and cool. Then transfer it into a nessler cylinder and add 30mg of Ammonium Persulfate and 15 ml of Botanic Potassium Thiocynate solution. Shake for 30 sec and allow the liquid to separate.
  • Blank reading : take 10 ml distilled water. Add 1ml concentrated Nitric acid boil the solution and cool. Then transfer it into a nesseler cylinder and add 30 mg of Ammonium Persulfate and 15 ml of Botanic Potassium Thiocynate solution . Shake for 30 sec. And allow the liquid to separate. Then add Standard Iron Solution until the colour of Butanol Layers in Both Cylinder (Sample & Blank)

Range of Products:
Sodium Silicate liquid both Neutral & Alkaline
We manufacture large range of Sodium Silicate both in Neutral and Alkaline grade of the typical qualities.

We also manufacture Sodium Silicate as per the customer's requirements and specification.

Sodium Silicates Concentration Mole Ratio Baume
Alkaline Sil 40 – 54 % 2.1 to 2.6 45 – 57
Neutral Sil 27 – 39 % 3.0 to 3.5 30 – 41.5
Using Procedure:


Sodium Silicate is a compound mixture of sodium oxide i.e. Na2o with silica sand i.e. Sio2 with water. Sodium silicate is also called water glass. There are two process to manufacture liquid Sodium Silicate. 

To manufacture a lower ratio of Sodium Silicate by Hydrothermal process.

Mixture at Na2Co3 (Soda Ash) with Sio2(Silica sand) in furnace fuses  of more then 1100oC gives sodium silicate glass in lumps form which is  easily dissolved in hot water.We manufacture large range of sodium silicates, as per the customer's specific requirements.
