Relying on the technologic-processing of Phosphoric Acid (Electronic Grade), XINGFA has vigorously developed so many related products, such as Phosphoric Acid (Electronic Grade), Aluminum-etching-liquid, Sulfoxide (Electronic Grade), Sulfuric Acid (Electronic Grade), Sodium Hypophosphite (Hard-disk Grade) and so on, and we have tentatively conducted R & D works upon Gases-in- Electronic Grade, such as phosphorane, Ammonia, and Hydrogen Chloride and so on, as well as Phosphoryl Chloride (Electronic Grade).
