About Phosphoric Acid 85% Semiconductor/Electronic Grade
Phosphoric acid, also known as orthophosphoric acid, is a weak triprotic acid. At 85%, it is a colorless and odorless viscous liquid. Semiconductor grade indicates that the solvent is of sufficient purity for the semiconductor manufacturing and electronic industries, having only trace levels of impurities.
Common Uses and Applications
- Etching of semiconductors
- Sanitizing agent for silicon wafers
- Rust converter
- Anti-rust agent
- Cleaning agent
Industries
- Electronic industry
