I have to propose a solid state reaction to make Y₃Fe₅O₁₂

I have suggested: Y₂O₃ + Fe₂O₃ -> Y₃Fe₅O₁₂

I think that is impossible to balance, so would this be a probable chemical reaction equation:
3Y₂O₃ + 5Fe₂O₃ -> 2Y₃Fe₅O₁₂ + 12O₂

Actually, how is it commonly synthesized? I can only find modern sol-gel papers like this one: Influence of Complexing Agents and pH on Yttrium-Iron Carnet Synthesized by the Sol-Gel method

Incredible synthesis procedure you've found Mitch, I would have assumed garnet, whether gem-quality or YAG laser material, was made in a furnace out of a slow mix of Aluminum and other oxides.

I believe the most effective synthesis for large YAG crystals is still the normal solid state reactions. But, sol-gel methodologies have been all the rage for the past 10-15 years for all things small and crystalline.

I always enjoyed reading Crystal Growth in Gel Media by Heinz K. Henisch, that was a great book.  I remember when I had the boss order for me a U-tube.  I showed him the book and what I wanted to do -- I so wanted to grow calcite crystals in an agar gel (never did get that to work).  He said if I could reliably produce 1 mm clear calcite crystals, I'd have a moneymaking machine.  I only wish I could read or download the reference you cited.

I've added you to the Chemist membergroup, it places beakers under your name and grants access to the hidden chemists only forum. You'll find a treat there for you.

lol, I tried. Logically too; I must of been keeping to much stuff in my head to think it through correctly.

Plus, it helps keep this forum active.
