1.Tungsten tube is widely used in the thermocouple protection tube, sapphire crystal furnace and high temperature furnace, etc. 2.Tungsten is usually sintered processed and with 8mm wall thickness. 3.Tungsten tube contributes stability to the hot zone. 4.While high in thermal inertia, tungsten tube may prolong the growth cycle of the sapphire.
that precisely matches the congruently -melting composition of the desired crystal, (2) a slow growth rate (10 to 20 mm /day), and (3) a steep (5 to 15 °C /mm) temperature gradient at the solid -liquid interface in the crystal growing furnace .
POLEMA JSC produces rolled sheet with the thickness of 0,5 - 45 mm and tungsten crucibles of pure raw materials - internal tungsten powder with the purity above 99,98%. Sapphire crystals raised in tungsten furnaces are of higher purity than those raised in plants with tungsten-molybdenum crucibles and molybdenum shields .
CONSTITUTION: A single crystal growing furnace has a closed growing furnace filled with insulation materials, a crucible opened upward, a graphite heating body opened up and downward and a heat-exchanger cooled by a hollowed water cooling pipe. The crucible is rectangular to grow single crystals of sapphire having rectangular cross section.
The present invention addresses the problem of providing a crucible which is for use in growing a sapphire single crystal and which has a structure that can inhibit molten sapphire from being contaminated with a component of the crucible.

the bottom. Because the sapphire boule sticks to the crucible at the end of the growing process, boules can crack at the cool down process and the crucible can only be used once. Any of these sapphire crystal growing technologies have in common that core components - particularly crucibles - are requiring high-temperature refractory metals.
