Boron Rem From Ultrapure Water By Selective Resin, …
The typical levels of boron in the raw water supplying AMD's facility in Austin, Texas are in the neighborhood of 0.25 ppm. Since boron is used in the production of microprocessors as a doping agent, AMD decided that any boron that remained in the Ultrapure Water (UPW) used in FAB 25 might be detrimental to the performance and yield of product.Web

Boron (B) and water
Boron salts are generally well water soluble. Boric acid has a water solubility of 57 g/L, borax of 25.2 g/L, and boron xide of 22 g/L. Boron trifluoride is the least water soluble boron compound, with a water solubility of 2.4 g/L. Some boron compounds, such as boron nitrite are completely water insoluble.Web
