Potassium silicate is a water-soluble and glass-forming silicate salt that is commonly used as an adhesive in welding rods.
This compound has been in use for at least a century.
- Rendering the woodwork of houses secure against catching fire can be done at an insignificant cost, and with little trouble. Saturate the woodwork with a very delicate solution of silicate of potash as nearly neutral as possible, and when this has dried, apply one or two coats of a stronger solution."[1]
In horticulture, potassium silicate is used as a soluble source of potassium and silicon. It also makes the growing medium more alkaline.
Some cleaning formulations use potassium silicate, which also serves as a corrosion inhibitor in cosmetics.[2]
Formula is K2SiO3.
