How to identify true and false titanium dioxide

Physical method:

The easiest way is to compare the feel, fake titanium dioxide is more slippery, and true titanium dioxide is more astringent.

The water is washed, and the hand is stained with titanium dioxide. It is easy to wash off falsely. It is really not easy to wash away.

Take a glass of clear water and put titanium dioxide into it. It's true that it floats. If it is precipitated, it will be false (if it is activated and modified, it will not work).

chemical method:

Mixed with light calcium or heavy calcium: Add dilute sulfuric acid or hydrochloric acid, bubbles can make the clarified lime water turbid, because calcium carbonate reacts with acid to produce carbon dioxide.

Mixed with lithopone: Add dilute sulphuric acid or hydrochloric acid, smelly rotten eggs.

Made of latex paint, plus iron red, dark color, indicating poor hiding power is false or poor quality titanium dioxide.
