Popis: A high‐pressure, magnetic Czochralski apparatus was built for the growth of . Various operating problems were successfully overcome, such as seed‐holder vibrations, poor visibility, explosions, control of solid‐liquid interface shape, efficient coupling of rf power into the melt, and correcton of large temperature gradients. Experiments were carried out demonstrating the large effects of gaseous pressure on the temperature gradients. At 35 atm pressure, the autoclave behaved as if it were filled with a liquid and not a gas, both with respect to visibility and heat flow. Coarse‐grained polycrystalline ingots were grown, with grains limited in size to 1 cm3 because of spurious nucleation of new grains.
