The present invention relates to a crucible for an ingot growing apparatus capable of increasing the life span of a graphite crucible. One embodiment of the present invention provides a crucible for an ingot growing apparatus including: a quartz crucible containing a silicon melt and having a lower surface part with a curved shape; a graphite crucible accommodating the quartz crucible and having a body shape divided into at least two parts with respect to a lower surface thereof; and an inner supporter supported between the lower surface of the quartz crucible and the graphite crucible.

An exemplary embodiment of the present invention provides a silicon single crystal growing apparatus and method. The apparatus comprises: a chamber; a crucible that is disposed in the chamber and receives melted silicon; a heater disposed outside the crucible to heat the crucible; a heat shield part disposed in the chamber; and an auxiliary heat shield part disposed above the crucible to move upward and downward, wherein the auxiliary heat shield part is disposed to be separated from a body part of a single crystal that has grown from the melted silicon, and a rising speed is controlled such that a defect-free zone in the single crystal body part increases. The auxiliary heat shield part can reduce a deviation of a temperature gradient in the body part, whereby increasing the distribution of a defect-free zone in the body part.
