Stable Isotopic Boric Acid for Semiconductor Doping Process

Enriched Boric acid-11 is a stable isotopic boric acid synthesized from high-abundance ¹¹B feedstock, with CAS No. 13813-78-0 and molecular formula H₃¹¹BO₃. It appears as white powdery crystals or lustrous flaky crystals. ¹¹B exhibits nearly zero thermal neutron absorption cross-section (thermal neutron capture cross-section of merely 0.005 barns). It serves as a critical raw material for semiconductor ion implantation and special material fabrication, widely adopted in advanced-node chip manufacturing and special alloy industries.
