Advantages over Sodium Silicates
Dissolves more rapidly in water, or with equal speed at lower temperature.
Coatings do not develop white carbonatefilm or efflorescence on exposure to the atmosphere. With Sodium Slicates,hydration of Sodium Sulphate is destructive to Silicate based mortars in sulphuric acid service. Potassium Silicate eliminates this problem. Consequently, Potassium Silicate is preferred for decorative coatings, paints and ceramic binders.
Potassium Silicates are used in formulation of liquid heavy-duty detergents and also in built liquid and paste Potassium soaps.
Absence of Sodium in Potassium Silicate is essential in settling television phosphor screens mid in the manufacture of certain special silica gels.
Where Potassium is a necessary ingredient, it is convenient to introduce it as a silicate. This is certain catalyst gels and in Welding rod coatings.
Most siliceous mole ratios are available. It is possible to manufacture Potassium Silicate in ratios which are relatively rich in silica and low in alkali.
At the same silica to alkali mole ratio, Potassium Silicates soften and flow at a higher temperature than corresponding Sodium Silicates. Potassium Silicate can, therefore be used in high-temperature binders of various types.
Potassium Silicate solutions are not tacky, and mortars prepared from them do not stick to the trowel. This can reduce labour costs for brick laying in acid-fast construction.
Anhydrous Potassium Silicate glass is less conductive, i.e. it has greater electrical resistance, and can therefore be used in cementing electrical components, bonding reconstituted mica , inputting compounds, etc.
