Title:
PREPARATION OF NONMAGNETIC MN-ZN FERRITE SINGLE CRYSTAL
Document Type and Number:
Japanese Patent JPH06239697
Kind Code:
A
Abstract:
PURPOSE: To prepare a high-quality single crystal without using an expensive and complicated device such as a high-pressure container in a method for producing a nonmagnetic Mn-Zn ferrite single crystal.
CONSTITUTION: In growing a single crystal by gradually passing a raw material in a molten state through a furnace having a temperature gradient, the single crystal is grown while dropping a crucible having the melt at 0.5-1.0mm/hr falling speed in the furnace having 2.4-2.6°C/mm temperature gradient approximately at 1,600°C.
