In the production process of some micronized powders, some crystal seeds are used, but what is the role of active crystal seeds in aluminium hydroxide grinding micronized powders, and what is the relationship between them? What is the relationship between aluminium hydroxide powder and active crystal species? Let’s take a look at the following together.

Active crystalline species are crystals of aluminium hydroxide with high dispersion, great surface area and many active sites

Active crystal seeds are some aluminium hydroxide crystals with high dispersion, great surface area and numerous active points, which are said to be active due to their fast and uniform growth rate. However, exactly how active it is still depends on factors such as its preparation method, conditions, storage time and the structure of the seeds and the particle size of the crystal seeds.

Formally due to the various characteristics of the active crystal species, its quality and quantity can have an important influence on the strength and decomposition rate of the aluminium hydroxide micronaire, which we should control according to the actual situation.

In the production process, industrial aluminium hydroxide coarse grains are generally wet ground to obtain a special crystal seed slurry for addition to the crystal seeds during decomposition.

In order that the activity of the crystal seeds can be guaranteed, the crystal seed slurry should not be kept for more than three days. As the ground aluminium hydroxide particles become extremely fine, the aluminium hydroxide micronized makes a significant improvement in both dispersion and activity, so the quality will also improve.
