1. Titanium dioxide anatase, titanium dioxide antase coated, titanium dioxide rutile sulfuric process, titanium dioxide rutile chlorination process:

According to the requirements of the coating properties, to choice the satisfied for the coatings and coating properties is very important. From the table, with the chlorination process rutile type titanium pigment production product is the best, currently we could see rutile chlorination is the best white pigement on the market . The comprehensive performance is excellent, the first choice in the white pigments, also the necessary pigment in light color.Because of the different surface treatment technology, titanium dioxide has different models. According to the characteristics of the mixture of coating, such as the high gloss, high covering power, or high pulverization, to choice the relevant type.Rutile sulfuric acid process, due to the conversion rate of anatase to rutile is lower than chlorination process, so the whiteness of the product and the stability of the light from chlorination process is a bit difference, but the price is lower.

Because the difference both crystal category, usage and dosage also have different distinction, in commonly used white pigments, anatase ,the minimum relative density, chemical properties is very stable, and lower price than titanium rutile , so there is the certain markets in many fields of industry like the cosmetics, paints, papers and others.

Applications:

1. Characteristic requirements for titanium dioxide in coatings and paints 

Titanium dioxide , coatings as he biggest parts, especially the rutile type.The global coating industries occupy 58% - 60%, mainly because the aspects of the performance is much better than the other white pigments. So the coating using by titanium dioxide is much higher than ordinary filler, because titanium dioxide is an integral part of in the coating, covering and adornment, its role is not only more important is to improve the physical and chemical properties of paint, bust also to improve the mechanical strength of the coating, adhesion, anticorrosive, light and weather resistance.So during of the production of coatings, It’s reasonable for us to choose the suitable type and specs!

2. Titanium dioxide quality requirements: Plastic, PVC, masterbatch

3. Titanium dioxide quality requirements: Paper production

Paper is the third largest parts for titanium dioxide, As the paper filter, mainly use in high grade paper and thin paper. To join titanium dioxide in the paper can make the paper good whiteness, good gloss, high strength, thin and smooth, not penetrate when printing, light quality.Titanium dioxide for Paper generally use the titanium dioxide without the surface treatment, can have the effect of fluorescent whitening agent, increase the whiteness of paper, but laminated paper use requires the surface treatment of rutile titanium, to meet the requirements of light resistance and heat resistance.

Different paper use, different type titanium dioxide, titanium dioxide rutile, good oxidation resistance good weather resistance, mainly used for decorative paper and high ash paper of weather resistance; While titanium dioxide anatase used for the low transparency and low ash paper,not high rquirement for  weather resistance.Although chlorination process and sulfuric acid process can produce rutile type, but the chlorination process titanium pigment , whiteness, the red crystal type of content, especially the stability of the finished product is better than that of the sulfuric acid method, suitable for use in the decorative paper and high ash;And coinage in the paper and the low ash must be used titanium dioxide by sulfuric acid, in order to meet the requirements of opacity for two kinds of paper.

4. Differences Between Rutile and Anatase Titanium Dioxide

(1) Rutile titanium dioxide is the most common form. It is preferably used in interference applications because of its high refractive index. It is also hard and has chemical resistant properties. The natural rutile is composed of ten percent of iron and traces of niobium and tantalum. “Rutile” comes from the Latin word “rutilus” which means “red.” When viewed by transmitted light, the rutile exhibits a deep red color. Rutile has many significant uses. In beach sands, if there is a large quantity of rutile, it serves as an important component of heavy mineral sand ore deposits. These sand ore deposits are eventually extracted to get the rutile mineral for the production of refractory ceramic, titanium metal, and pigment. The powdered form of rutile serves as white pigmentation for paints, paper, plastics, foods and other objects which need a white color. The nanoscale rutile particles are also used for the effective absorption of ultraviolet rays. With this characteristic, rutile is mixed to produce sunscreens and to prevent skin damage. Gems come with greater value if there is rutile among them because rutile can make an optical phenomenon known as asterism.

(2) Anatase is a type of polymorph which becomes a rutile when it is exposed at about 915 degrees centigrade. Its color is brown to black or yellow to blue. Anatase is the rarest form of titanium dioxide, but it has almost the same properties as rutile with regards to its hardness, density, and luster. However, you can distinguish the two minerals apart by their cleavage and crystal habit. Both anatase and rutile are tetragonal in structure, but the anatase has octahedrons that share four edges forming the four-fold axis. Quartz is usually associated with streaks of anatase. Quartz plus anatase make them a popular collection for gems and mineral collectors since these minerals exhibit wonderful lusters. Anatase is also used for the white pigmentation of paints, paper, and ceramics, but it is not advisable to use it outdoors because of its lower absorption rate than rutile.

Summary:

1. Titanium dioxide has two forms: rutile and anatase.

2. Rutile is deep red while anatase is yellow to blue.

3. Rutile has a high absorbance property than anatase.

4. Rutile and anatase are both used in the white pigmentation of paints, paper, and ceramics.

5. Sunscreens contain rutile because of its absorbance of ultraviolet rays.

6. Rutile and anatase provide extra luster to other gems and minerals since they are capable of asterism.
