Acid Resistant Hafnium Foil
Acid resistant hafnium foil is a special foil material made from high-purity metal hafnium (≥ 99.9%) as the substrate, through precision rolling and surface treatment. Its core value lies in its excellent resistance to strong acid corrosion, which enables it to work stably in high-temperature, high concentration acidic environments for a long time. It is a key material in the fields of chemical engineering, nuclear energy, and high-end manufacturing.
Description
This material needs to possess the following core characteristics：
1. Extremely resistant to strong acid corrosion
It has excellent resistance to strong acids such as nitric acid, hydrochloric acid, sulfuric acid, aqua regia, etc. The annual corrosion rate is less than 0.01 mm in 70% boiling nitric acid, and the service life is more than 10 times that of stainless steel.
2. high-temperature stability
The melting point is as high as 2233 ° C, and it maintains structural integrity in a concentrated acid environment at 200 ° C without any tendency for intergranular corrosion.
3. High purity and low pollution
Purity ≥ 99.9%, strictly control impurities such as iron, nickel, chromium (single<50 ppm), avoid galvanic corrosion and medium pollution.
4. Processability and diverse forms
It can be rolled to a thickness of 0.05-1.0 mm, supports stamping, welding, and winding forming, and is easy to process into complex components such as liners and gaskets.
Anti corrosion hafnium foil is mainly used in the following fields：
1. Chemical anti-corrosion equipment
- Reactor lining: Covering the inner walls of nitrification and chlorination reactors to prevent equipment from being corroded and perforated by acidic media.
- Electrolytic cell electrode plate: used for electrolyzing high-purity chemicals (such as perchloric acid), with excellent stability in high-temperature acidic electrolytes.
2. Nuclear fuel reprocessing
- Spent fuel dissolution tank liner: resistant to dual corrosion from high temperature concentrated nitric acid and radioactive media, ensuring the safety of nuclear waste disposal.
3. Semiconductor wet process
- Acid pickling tank carrier: carries silicon wafers for acid etching and cleaning, without metal ion contamination, ensuring chip yield.
4. Manufacturing of special materials
- Powder metallurgy crucible liner: used for synthesizing special ceramics or metal powders in high-temperature acidic media.
