Raw Materials | Sodium carbonate Orthoboric acid Hydrofluoric Acid |
white or light gray powder, slightly soluble in water.
synthesis method: anhydrous hydrofluoric acid is reacted with aluminum hydroxide to generate fluoroaluminate, which is then reacted with potassium hydroxide at high temperature, and then filtered, dried, melted and crushed to obtain potassium fluoroaluminate product.
used as an insecticide, also used in ceramics, glass industry and aluminum brazing.
