Any thoughts on this yet?
I think we are ready to try this on our side....

Subject: Iodic Acid
We would like to use Iodic Acid in SNF. This chemical is commonly used as an echant for III-V materials like InP. MSDS attached.
1.) Iodic Acid comes in dry crystal form
2.) One mixes the crystals with water to form the acid (0.2 M/Liter) in a glass, non-transparent bottle (Iodic acid should be kept from light)
3.) We will mix the crystals & water to create the solution at the GaAs bench
4.) At the GaAs bench, we will combine: HIO3 (0.2M/L) : HCl : H2O - 1:1:x where x goes from 1 to 100.
5.) All work will be done at room temp
6.) We will store the mixed solution in the personal chemical pass-through area, along with the dry crystals
What do you think?
