I have some poor quality grown sapphire capillaries (~2mm od x 1mm id, 80mm long, capped at one end). I am wondering if I can anneal these to remove microfractures. What temperature would be needed and should the annealing be done in vacuum, inert gas (He, or Ar) or in hydrogen? Obviously I am also looking for another supplier — do you sell small quantities (5-10 units) of single crystal sapphire capillaries in sizes similar to above?
Unfortunately, the annealing cannot help to remove the microfractures.
Yes, we can supply the sapphire micro tubes: 2.0mm OD +/-0.15mm x 1.0mm ID +/-0.15mm x 80mm long +/-1.0mm / OD and ID are “as grown” / Capped at one end
Qty. 5- 10 pcs

What raw material is used to make your sapphires? It is alpha aluminum oxide, I know, but is this alpha A12O3 made out of bauxite, or is it chemically synthesized?
