Silicic glass, solution

Ellis and Wilson studied cements formed from concentrated solutions of poly(vinylphosphonic acid) (PVPA) and oxides and silicate glasses, which they termed metal oxide and glass polyphosphonate cements (Wilson ... 

Many methods exist for the production of phosphor screens [5.296]. For monochromatic tubes a suspension of the phosphor in alcohol or water, with addition of water glass solution, is placed in the tube and is deposited by sedimentation on the inner surface of the faceplate. The adhesion is effected by the slowly precipitating silicic acid. 

To study these reactions use a M solution of sodium silicate, Na2Si03. Commercial (30%) water-glass solutions should be diluted with a five-fold amount of water. 

Sodium silicate (m). Dilute 200 ml commercial (30%) water glass solution with water to 1 litre. 

There are a number of papers which report the use of Si NMR in studies of the structures of various soluble silicates and alkali silicate glasses. (93, 97-103) Early workers concluded that in soluble sodium metasilicate solutions only simple monomeric silicate structures are present. (104) The presence of polymeric structures was subsequently identified using Raman spectroscopy (105-107) and trimethylsilylation experiments. (108) Marsmann (97) first reported the existence of dimer, linear trimer, tricyclic, and polymeric structures based on Si NMR...
