My Gallium Nitride investment

    It turns out that with little effort one can make semiconducting materials that can be then manipulated to be put into solar panel arrays.

    So I bought something that could help me make some. Gallium in its elemental form. Gallium is a rare-ish metal that can bond to nitrogen to make the compound Gallium Nitride (GaN)

    Thought it was a five step process, to make these chemical semiconductors, turns out we had chemicals that did the job better and easier due to my chem teacher this term, and we have now achieved the first step which was easy, dissolve the gallium in Hydrochloric Acid, the second step will be a bit longer, exposing Lithium metal to a Nitrogen atmosphere to make Lithium Nitride for the third step which will be to combine two of the four resulting chemicals (GaCl3 and LiN), of which the LiN will go into the GaCl3 to combine into a solid to make Gallium Nitride. From there I will check out what the chemical acts like and research its possible uses in renewable energy.

    Question, does anyone know how/if I should go about making a "glove-box"?

    My husband actually does research into thin films for semiconductors/solar panels. He says there are less toxic materials than what you're using to achieve what you want. He also says that as long as you are using materials that aren't dangerous when exposed to air, you shouldn't need a glovebox, but if you're really interested, here's a viable alternative: Atmosbag glove bag - an inflatable polyethylene glove box alternative

    Tell him thanks, and I've heard of the glove bag.
    What materials are safer?
    I've heard that I could've used a mixture of indium and gallium to make the nitride from and it could be coaxed into a solar concentrator and would absorb the largest amount of light from the sun. But as far as safer than Gallium, hydrochloric acid, lithium, and sodium nitrate, HCl is the cheapest way I know to bind the necessary halogens to the Gallium, and Lithium only oxidizes when exposed to normal air, but I'm only going to expose it to N2 obtained by heating the NaNO3. All of these I have access to in my college's chemistry lab, via my chem teacher.

    Change of plan, I'm going to generate the N2 by introducing Sulfamic Acid to the Sodium Nitrite.

    Update again: Professor agrees we should buy Li3N rather than create it ourselves due to the difficulty of reliably obtaining N2 while keeping costs down.

    I was up at our surplus warehouse two weeks ago and there were a few glove boxes. If you don't have one, I can check and see if they're available for sale the the public yet. You're probably looking at a few hundred for shipping, though.

    Naw, we don't need a glove box at this point.
