1. A hot press sintering apparatus comprising:
a chamber; a mold member located in the chamber and including a mold space section to be filled with a raw material; a press member for pressing and processing the raw material in the mold member; upper and lower moving members to move the press member up and down; and a heating member for heating an interior of the chamber, wherein the mold member includes a first mold part and a second mold part inserted into the first mold part, the second mold part being formed with the mold space section; wherein the press member includes a press section adjacent to the mold space section and an adiabatic section disposed at the press section; wherein the adiabatic section has a thermal conductivity lower than a thermal conductivity of the press section; wherein the press section includes graphite, the graphite having an impurity with a concentration equal to or smaller than 20 parts per million (ppm); wherein the adiabatic section is formed with a composite material including a carbon fiber reinforced carbon composite material, and wherein the adiabatic section is positioned between the press section and the upper and lower moving members, wherein the composite material is woven in a vertical direction, wherein the composite material has a thermal conductivity equal to or smaller than 10 W/Mk, wherein a width of the adiabatic section is smaller than a distance between two outmost lateral sides of the upper moving member or than a distance between two outmost lateral sides of the lower moving member, wherein the adiabatic section includes a first part positioned at one surface of the press section and a second part surrounding a lateral side of the press section, wherein a thickness of the first part and a thickness of the second part are both in a range of 5 mm to 200 mm, and wherein the adiabatic section has a cap shape.
