A cooling apparatus for a hot stamping die is configured such that a refrigerant in a two-phase coexisting state of a liquid phase and a gas phase is supplied to a cooling channel formed in the hot stamping die to cool the hot stamping die using latent heat of the refrigerant. The refrigerant maintains a constant temperature in the cooling channel of the hot stamping die, which ensures uniform cooling of the hot stamping die.

Disclosed herein is a method for manufacturing SiC powders with a high purity, and more particularly, a method for manufacturing SiC powders with a high purity by reating a solid phase carbon source as raw materials with gas phase silicon sources generated from a starting material composed of metallic silicon and silicon dioxide powders and, in which it is easy to control the size and crystalline phase of the SiC powders by changing the compositions of the gas phase silicon source to the solid phase carbon source mole ratio, and the temperature and time for the heat treatment.
