| titleOfInvention | Method for producing high density boron carbide sintered body by ultrasonic |
| abstract | In the present invention, the boron carbide powder and the solvent are mixed in a volume ratio of 1: 1 to 1:10 to form a mixed solution and ultrasonic waves are applied to weaken or break the interatomic bonds of boron oxides 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 , A method of manufacturing a high-density boron carbide sintered body using ultrasonic waves, comprising the step of obtaining the boron carbide sintered body by cooling the furnace and the step of sintering the boron carbide, while the pressure on the molded article of the boron carbide powder in the sintering temperature.n n n n Boroncarbide, boron oxide, hot pressing, sintering aid |
