Regarding electronic-grade hydrochloric acid
Thread Content
What is electronic-grade hydrochloric acid, and is it different from reagent-grade hydrochloric acid? How can 32% industrial hydrochloric acid be converted into 36% electronic-grade hydrochloric acid?
Reply to 1# Laughing All Around: It depends on what standard the so-called electronic-grade hydrochloric acid needs to meet. Do you want to achieve a solar level (solar grade ≥1ppb) or a semiconductor level ≤0.1ppb?
It is easy to produce at the electronic grade; what was mentioned on the second floor seems very difficult to achieve – there must not be even one gram of impurities in 100,000 tons: L
It’s indeed not that easy, but with the right selection of equipment and experience in distillation processes, it is difficult to achieve a concentration of 1 ppb for hydrochloric acid, though it’s not entirely impossible
Don’t think it’s difficult; this standard is the standard for electronic chemicals: lol
