Anyone machined this stuff? I have an enquiry from a customer but I hear the stuff, although not intrinsicaly toxic, can libreate Arenic and Gallium compounds which, when in contact with water, acids or alkalais can give off nasty stuff.
If I was to ingest some Gallium Arsendie dust while turning it, would the moisture in my lungs and/ or acid in my stomach constitute a risk?
I have searched all day for info on this stuff and although it says there's nothing on GaAs being toxic, I have found comprehensive (and sometimes contradictory) information on Arsenic and Gallium compounds being bad.
There's no data on the LD50 or LC50 values for GaAs.. anyone know where I can find it? (LD50 and LC50 are measures of how much material is required to kill 50% of the animals it's being tested on via various routes- see

Many thanks in advance.
