Ceramic core, manufacturing method for the same, manufacturing method for casting using the ceramic core, and casting manufactured by the method
A ceramic core includes sintered ceramic powder and a hole opening on a surface of the ceramic core and having an opening portion with a maximum size of 100 μm or less. A manufacturing method for a ceramic core includes: preparing an injection molding composition by mixing ceramic powder and a binder; manufacturing a ceramic compact by performing the injection molding of the injection molding composition; and manufacturing a ceramic core by sintering the ceramic compact, wherein cumulative percentage of coarse powder with a particle diameter of more than 50 μm included in the ceramic powder is 30% or less on an integrated volume particle size distribution curve of the ceramic powder.
