How to distinguish true and false titanium dioxide?

Physical method:

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

Water washed, hands dip titanium dioxide, fake easy to wash away, really not easy to wash away.

Take a cup of water, throw titanium dioxide into the float to the truth, the precipitation down for the fake (if it is activated by the modified product is not working).


chemical method:

Mixed with light calcium or heavy calcium: add dilute sulfuric acid or hydrochloric acid, there are bubbles can make clear lime water becomes turbid, because the calcium carbonate reacts with the acid to produce carbon dioxide.

Mixed with Lide powder: add dilute sulfuric acid or hydrochloric acid, smell of rotten eggs.

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


There are two better ways:

Using the same PP + 30% GF + 5% PP-G-MAH + 0.5% titanium dioxide, the lower the strength, the more true the titanium dioxide (rutile).

Choose a transparent resin, such as transparent ABS + 0.5% titanium dioxide, measuring light transmittance, the lower the light transmittance, the more true the titanium dioxide.
