Description

Hydrofluoric Acid (HF, Aqueous Hydrogen Fluoride)

Hydrofluoric Acid is aqueous solution of hydrogen fluoride gas, chemical formula HF, CAS No.7664-39-3, colorless transparent irritant fuming liquid. Though classified as weak acid, it owns exclusive ability to dissolve silica and silicate materials which cannot be corroded by other common inorganic acids.

Our industrial HF is produced with stable concentration (20%/40%/50%/70% customizable), low heavy metal and insoluble impurities, consistent etching speed batch to batch for continuous industrial mass production.

Core Industrial Application Fields

1. Glass & Crystal Industry Core etchant for decorative glass frosting, engraved patterns, craft crystal, optical lens and lab glassware. Reacts with SiO₂ to form matte, frosted or carved texture surfaceAlibaba.co….
2. Ceramic & Sanitary Ware Surface cleaning agent to remove silica impurity on ceramic blank, matte treatment for ceramic glaze surface.
3. Metal Surface Treatment Stainless steel, aluminum alloy pickling & descaling; remove oxide film and welding stain, brighten metal surface.
4. Fluoride Chemical Synthesis Key raw material to produce sodium fluorosilicate, cryolite, aluminium fluoride and all kinds of industrial fluoride salts.
5. Semiconductor & Electronic Industry Silicon wafer cleaning, remove native oxide layer on chip surface for precision microelectronic manufacturing.
6. Petroleum & Mineral Refining Catalyst for oil alkylation process; mineral leaching for rare metal extraction.

Critical Safety Warning (Mandatory Display)

1. HF is extremely toxic & highly corrosive dangerous chemical (UN1790). Liquid and vapor cause severe deep skin burns, eye damage and even fatal systemic fluorosis; injury may penetrate bone tissue抖音百科.
2. Operation must be in fully ventilated workshop; wear full set special protection: fluorine-resistant rubber gloves, acid-proof apron, full-face shield, respirator mask.
3. Storage & transport only with HDPE / PTFE plastic containers, never use glass or metal barrels. Separate from strong alkali, oxidants, food materials.
4. First aid preparation: Calcium gluconate gel & emergency shower/eyewash must be placed on site. Once skin contact, flush with massive clean water over 20 mins then apply calcium gluconate and seek medical treatment immediately中国科学院….
5. All shipment complies IMDG dangerous goods rules, complete hazard certification documents provided.
