How to distinguish high-quality mica powder?

Identification method

According to our experience, there are roughly the following methods for mica powder identification, for your reference only:

 

  1. The whiteness of mica powder is not high, about 75 or so. I often receive questions from customers, and the whiteness of mica powder is about 90. Under normal circumstances, the whiteness of mica powder is generally not high, only about 75. If mixed with other fillers such as calcium carbonate, talcum powder, etc., the whiteness will be greatly improved.

 

  1. Mica powder has a flaky structure. Take a beaker, add 100ml of pure water, and stir it with a glass rod. It can be seen that the mica powder has a good suspension; other fillers include transparent powder, talcum powder, calcium carbonate, and other products. Neither mica powder is superior.

 

  1. Put a little amount on the wrist and it will have a pearlescent effect; mica powder, especially sericite powder, has a certain pearlescent effect and is widely used in cosmetics, paints, plastics, rubber, and other industries. If the pearlescent effect of the purchased pearl mica powder is poor or without any pearlescent effect, you should pay attention at this time.
