This fusion method produces an acid-soluble glass bead which is dissolved in nitric acid. It avoids the use of hydrofluoric and perchloric acids. The disadvantages are the cost of platinum labware, and the large quantities of LiB02 used to produce the glass bead increase the total dissolved solids and may contribute to polyatomic species. Dilution to counter these effects may reduce the elements of interest below the instrumental detection limits. 

How is glass manufactured in the industry What grades of glass do you know What is the state of aggregation of glass What is the composition of commercial soluble glass ... 

Hydrogel of Silicic Acid. Pour 5 ml of a concentrated solution of soluble glass into a test tube, rapidly pour 3 ml of a 24% hydrochloric acid solution into it, and stir with a glass rod. What is observed Write the equation of the reaction. How can you explain the formation of a gel ... 

Hydrosol of Silicic Acid. Add 1 ml of soluble glass to 6 ml of a 37% hydrochloric acid solution. Why does no gel form in this case Does the acid solution obtained... 

Soluble Glass, which is a simple silicate of potesaa or of soda, or a mixture of those two silicates. 

The opal is very similar to hyalite, mutter glass, a hydrate of silica. The composition is remarkable it ia a simple silicate of potaesa, which, from being imperfectly melted, remains somi-tranaparent, with pieces of quartz dispersed through the mass. It does not attract moisture, and is not attacked by boiling water. It differs from Ttjch s soluble glass, by containing ten per cent, more silica. 

Action of Air or Oxygen.—Air or oxygen, cold or hot, provided they are dry, exercise no action on glasses. It is Dot so with moist air, as will he seen further on, especially with reference to soluble glass. In this case, however, the reagent is water. 

Much attention has been paid to the synthesis of fluorine-containing condensation polymers because of their unique properties (43) and different classes of polymers including polyethers, polyesters, polycarbonates, polyamides, polyurethanes, polyimides, polybenzimidazoles, and epoxy prepolymers containing pendent or backbone-incorporated bis-trifluoromethyl groups have been developed. These polymers exhibit promise as film formers, gas separation membranes, seals, soluble polymers, coatings, adhesives, and in other high temperature applications (103,104). Such polymers show increased solubility, glass-transition temperature, flame resistance, thermal stability, oxidation and environmental stability, decreased color, crystallinity, dielectric constant, and water absorption. 

Si(OH)4. When silica, in the form of flint, or fine sand, or powdered rock-crystal is either fused with caustic soda or potash, or heated under pressure with a solution of one or other of the alkalies, an orthosilicate is produced, possessing the formula Si(ONa)4 or Si(OK)4. These silicates are soluble in water, 2nd as they resemble glass in appearance, they are usually named soluble glass. If hydrochloric acid is added to the solution of one of...
