The difference between rutile titanium dioxide and anatase titanium dioxide.

The difference between rutile titanium dioxide and anatase titanium dioxide ：

1.The crystal types of the two are different. Titanium dioxide has three crystal structures, plate titanium type, anatase type, and rutile type. Due to its unstable crystal structure, plate titanium type cannot exist stably for a long time in nature, so it is not used in small quantities and has no industrial value. The rutile type tends to be more stable.

2. Rutile and anatase titanium dioxideThere are differences in particle size distribution: Since the crystal form of rutile products is more hexahedral, it is easier to disperse evenly than anatase, and the agglomerates formed are more uniform. The particle size distribution is narrower.

3. Although the production processes of rutile and anatase sulfate are basically similar , but the specific parameters are very different.

4. Anatase products can only be produced by the sulfuric acid method, but There are currently two types of rutile products: sulfuric acid method and chloride method.

5. The final difference is the coating: anatase products are basically After calcination and settlement, it is packaged and sold after being crushed by Raymond mill. In order to better improve its dispersion, weather resistance and other characteristics, rutile products are surface treated with alumina or zirconium after calcination, and at the same time, some Organically processed.

In fact, the performance and use of the two The main difference between the two is in weather resistance. Rutile has better weather resistance. It can be exposed to sunlight for up to ten years and has good acid and alkali resistance. The only thing about anatase type that is inferior to rutile is that it is mainly used indoors, while rutile can be used both indoors and outdoors. It’s somewhere in between.
