  • Purification method and purification apparatus
    Patent number: 11090577
    Abstract: A novel sublimation purification method is provided. Moreover, a novel sublimation purification apparatus is provided. A purification method using a purification apparatus including a purification portion where a substance is purified by vaporization, a temperature adjustment means, a gas supply means, and a gas discharge means is provided. In the purification method, the inside of the purification portion is made to have a first pressure with use of the gas discharge means, a temperature gradient is generated in the purification portion with use of the temperature adjustment means such that the substance is purified, the pressure in the purification portion is then set at a second pressure with use of the gas supply means, and the purification portion is cooled with use of the temperature adjustment means. The second pressure is higher than the first pressure and the second pressure is higher than or equal to an atmospheric pressure.
