| titleOfInvention | Method for producing high density boron carbide sintered body using ultrasonic waves and the high density boron carbide sintered body manufactured thereby |
| abstract | The present invention, by mixing the boron carbide powder and the solvent in a volume ratio of 1: 1 to 1:10 to make a mixed solution and applying ultrasonic waves, to weaken or break the interatomic bonds of the boron oxide present on the surface of the boron carbide powder An ultrasonic cleaning step of releasing the oxide layer on the surface of the boron carbide powder by facilitating the formation of metaboric acid, and putting the ultrasonically cleaned boron carbide powder into a mold provided in the furnace and applying pressure to form a molded body of a desired shape; Operating a pump to exhaust the impurity gas present in the furnace, firstly raising the temperature of the furnace to a temperature at which the boron oxide present on the surface of the boron carbide powder volatilizes, and raising the temperature of the furnace to boron oxide. Secondary raising to a target sintering temperature above the volatilized temperature and below the melting temperature of boron carbide And a method for producing a high density boron carbide sintered body using ultrasonic waves, comprising: sintering boron carbide while applying pressure to a molded body of boron carbide powder at the sintering temperature, and cooling the furnace to obtain a boron carbide sintered body. It relates to a high density boron carbide sintered body. |
