Vemeuil technique

The Verneuil Technique. The Vemeuil technique is also known as flame-fusion. A very pure feed powder is first made by chemical decomposition. For the growth of corundum, ammonium alum [7785-25-0], NH4A1/(S04)2 12H20, is recrystallized from water containing added... [Pg.215]

The self-diffusion coefficient of oxygen in polished slices of Vemeuil single-crystals was determined at 1500 to 1770C by using the gas-solid isotope exchange technique. The results were represented by ... [Pg.189]

Rutile (TiOj) can be prepared in the form of single crystals by the Vemeuil (flame fusion) technique. Slightly reduced rutile is an n-type semiconductor with an energy gap of 3.05 eV and electron mobilities of -1.0 cmWs at room temperature.
