Electronics Industry


PQ Corporation manufactures many products used in the Electronics market.  KASIL® potassium silicate is available for use as a binder for phosphors, for circuit board cleaners, and wafer-polishing slurry feedstock. 
How It Works
Potassium silicates are used as phosphor binders and setting agents in the manufacture of cathode ray tubes (CRTs).  The Electronic Grades of potassium silicate are higher purity products with very low levels of iron, copper, and nickel.  This higher purity helps to ensure that no clumping or pinholing occurs on the inside of the screen.  Sodium silicates are also used to make precipitated silica and colloidal silicas for wafer polishing.
