白矾常用的炮制方法

白矾常用的炮制方法
## English Answer:
Calcination.
Calcination is a common preparation method for white alum. It involves heating the alum in a closed vessel in the absence of air or with limited air supply. This process drives off the water of crystallization and other volatile components, leaving behind a more concentrated and anhydrous form of alum.
Crystallization.
Crystallization is another important preparation method for white alum. It involves dissolving the alum in a solvent, such as water, and then allowing the solution to evaporate slowly. As the solvent evaporates, the alum crystallizes out of the solution. The crystals can then be collected and dried.

煅烧。

煅烧是白矾的常用炮制方法之一。

将白矾置于密闭容器内，在
无空气或空气供应有限的条件下加热。

此过程会除去白矾中的结晶
水和其他挥发性成分，留下浓缩且无水形式的白矾。

结晶。

结晶是白矾的另一种重要炮制方法。

将白矾溶解于溶剂（如水）中，然后让溶液缓慢蒸发。

随着溶剂蒸发，白矾会从溶液中结晶析出。

然后可以收集并干燥晶体。
