Resistance Heated Crystal Puller for Operation at 2000°C

Abstract
A resistance heated crystal puller has been used to grow crystals of NbO, Ti2O3, and Al2O3, which have melting points of 1945, 2000, and 2050°C, respectively. The puller incorporates a modified version of a tantalum tube furnace described previously, which is capable of operating in oxidizing, neutral, and reducing atmospheres up to 2400°C. The seed holder is water‐cooled.
