Abstract
PURPOSE: To easily produce a purplish red forsterite single crystal free from a bubble, an inclusion, etc. by melting a high density rodlike sintered raw material consisting of a specified amt. of MgO, SiO2 and CoO with infrared rays followed by crystallization on the interfacae of the molten part.
CONSTITUTION: Halogen lamp 2 is set at one focus of spheroidal mirror 1, and high density rodlike sintered raw material 3 consisting of MgO 5W80mol%, SiO2 50W 20mol% and Co 0.01W80mol% at the other focus. Material 3 and seed crystal 5 are fixed to upper and lower rotary shafts 4, 6, respectively, and they are sealed in transparent quartz tube 7. Infrared rays from lamp 2 are concentrated on the tip of material 3 to form melting zone 8, and by moving crystal 5 upward it is contacted to zone 8. After an equilibrium state is attained, by moving shafts 4, 6 material 3 is melted at the interface betweek zone 8 and material 3, and crystallization takes place at the interface between zone 8 and crystal 5.
