About recrystallization silicon carbide sintering furnace, recrystallization principle of this a lot of people do not know, today for you to answer the above questions, now let us take a look at it!
1. The process of dissolving crystals in solvent or melting by using the difference of solubility, and then crystallizing from solution or melt again.
2, also known as recrystallization.
3. Recrystallization can purify impure substances or separate salts that are mixed together from each other.
4. The effect of recrystallization is closely related to the choice of solvent. It is best to choose a solvent that is soluble to the main compound and slightly soluble or insoluble to impurities. After filtering off impurities, the solution is concentrated and cooled to obtain pure substances.
5. If the solubility of two salts mixed together in a solvent varies greatly with temperature, such as the mixture of potassium nitrate and sodium chloride, the solubility of potassium nitrate increases sharply with the increase of temperature, while the increase of temperature has little effect on the solubility of sodium chloride.
6. The mixture solution can be evaporated and concentrated at a higher temperature. The first precipitation is sodium chloride crystals. After the mother liquor after removing sodium chloride is concentrated and cooled, pure potassium nitrate can be obtained.
Recrystallization often needs to be carried out many times to obtain a better purification effect.
