摘要
The present invention relates to a method for manufacturing a raw sintered bulk and to a method for growing a single crystal using a sintered bulk. The present invention comprises: a raw material inserting step of inserting raw materials into an inner space of a crucible; an impurity removing step of removing impurities included in the crucible by heating the crucible at a first set temperature and a second set pressure for a first set time; a pressure increasing step of increasing the pressure of the inner space of the crucible to a second set pressure; a heating step of heating the crucible at a second set temperature by using a heating means while maintaining the inner space of the crucible at the second set pressure after the pressure increasing step; and a sintering step of forming a sintered bulk by sintering the raw materials while maintaining the crucible at the second set pressure for a second set time after the heating step.
