Problems solved by technology

At present, the pre-purification equipment purchased on the market does not set a temperature difference. During the purification process, the material is directly collected after volatilization. The purity of the material purified by this purification equipment cannot meet the purity requirements for the synthesis of high-performance materials.

Abstract

The invention relates to a device for purifying by utilizing component volatility difference, which belongs to the technical field of material purification equipment, and the device comprises a support, a vacuum suction tank, a vacuum pipeline, a purification cabin, a heating device and a vacuum air pump, the purification cabin is mounted on the support, the purification cabin is connected with the vacuum suction tank through the vacuum pipeline, and an outlet of the vacuum suction tank is connected with the vacuum air pump through a vacuum flange; wherein at least two stages of heating areasof different temperatures are arranged on the purification cabin, and a heating device is arranged on the outer side wall of each stage of heating area. By controlling the heating areas of different temperatures on the purification cabin, the purification material is volatilized in the high-temperature section under the vacuum condition and flows to the low-temperature section after being volatilized, and due to different temperature changes and different volatility of impurities, a pure material is condensed or solidified in the low-temperature section, and only the impurities remain in the high-temperature section finally, so that the material purification is realized.

Description

technical field [0001] The invention belongs to the technical field of material purification equipment, and in particular relates to a device for purification using component volatility differences. Background technique [0002] When preparing materials synthesized by multiple components, other trace components or metal impurities contained in each component raw material will affect the synthesis quality, resulting in the inability to obtain materials with excellent performance, and each raw material needs to be purified. [0003] When preparing high-performance multi-component single crystal materials, the raw materials need to be purified. During the purification process, two purifications are often carried out. The raw materials need to be purified twice, first for a pre-purification, and then for a fine purification. At present, the pre-purification equipment purchased on the market does not have a temperature difference. During the purification process, the material is ...
