Titanium dioxide rutile titanium dioxide with the use of

Titanium dioxide ( titania ) chemically stable in general not react with most materials . In nature , there are three crystalline titanium dioxide : titanium plate , titanium dioxide anatase and rutile titanium dioxide . Titanium plate crystal form is unstable , no industrial use value, anatase titanium dioxide (Anatase) referred to as A -type , and plastic additive  rutile titanium dioxide (Rutile) referred to as R-type , have a stable crystal lattice , it is important white pigments and porcelain glaze , compared with other white pigments have superior whiteness, color strength, hiding power, weatherability, heat resistance , and chemical stability, especially not toxic.
Coatings industry is the largest user of titanium dioxide , especially rutile titanium dioxide , mostly consumed by the paint industry . Manufactured with titanium dioxide paint , colorful, high hiding power , tinting strength , dosage province , variety, stability of the media can play a protective role , and can enhance the mechanical strength and adhesion of the film to prevent cracks, prevent UV and moisture through , extend film life.
Plastics industry is the second largest user of titanium dioxide added in plastics , plastic products can improve the heat resistance , light resistance , weather resistance, the physical  Metallic stearate and chemical properties of plastic products to improve and enhance products, mechanical strength, prolong life.
The paper industry is the third  Zinc stearate largest user of titanium dioxide as filler paper , mainly used in fine paper and the paper thin . In the paper by adding titanium dioxide , can make the paper has good whiteness, gloss , high strength , thin and smooth , printing does not penetrate , quality of light. Papermaking general use without a surface treatment of titanium dioxide anatase titanium dioxide, can play the role of optical brighteners , increasing whiteness of the paper . But requires the use of laminated paper surface treated rutile type titanium dioxide , in order to meet light and heat requirements. Or advanced ink titanium white pigment is indispensable . Durable ink containing titanium dioxide does not change color , surface wettability , easy to disperse . Ink industry has used titanium dioxide rutile , anatase have . Textile and chemical fiber industry is another important application of titanium dioxide . Chemical fiber titanium dioxide is mainly used as a matting agent . Since anatase type soft than gold, red , general use anatase . Fiber surface with titanium dioxide generally do not need treatment, but some special varieties in order to reduce photochemical effect of titanium dioxide , titanium dioxide to avoid fibers degrade the photocatalytic effect , the need for surface treatment.
