Anatase Titanium Dioxide A1
Anatase titanium dioxide A1 is a fine white powder pigment, which has good light scattering ability, and has a good whiteness, high color strength, strong coverage, non-toxic and tasteless, and has no stimulating effect on the human body. It is widely used in many industrial fields. Such as coatings, plastics, paper and ink, etc.
1.Basic performance
Anatase titanium dioxide A1, chemical name titanium dioxide, molecular formula Ti02, molecular weight 79.88. White powders, relative density 3.84. Melting point 1560 ° C. Water absorption is O. 02%. High temperature (> 700 ° C) heating is converted into a rutile crystal. The melting point is about 1800 ° C. Refractive index is 2.55. The average particle size is 0.15 ~ 0.23um. Moh’s hardness is 5 ~ 6. Chemical properties are stable, light, heat resistant, dilute acid, and resistant alkali. It has strong colors (hiding power) and dispersion. The temperature is higher than 400 ° C. Insoluble in water, organic acids and pouring acid, soluble in concentrated sulfuric acid, base and hydrofluoric acid. Non-toxic, the highest allowable concentration of 10 mg / m3 in the air.

3.Mainly used
- TiO2 pigment with papermaking generally uses unprocessed anatase titanium white powder, which can function as fluorescence, whitening, increase the whiteness of paper.
- The ink industry has a rutile type with titanium dioxide, and there is an anatase type titanium dioxide is an indispensable TiO2 in advanced inks.
- Anatase TiO2 A1 in textile and chemical fiber industry is mainly used as a matting agent, and since the atrial is more than gold-red, the anatase type is generally used.
- Titanium dioxide is used both as a colorant in the rubber industry, and has reinforced, anti-aging, filling, generally in anatase-based.
4. Package and storage:
Anatase titanium dioxide A1 are package by 25kgs.
It could be stored well for a long time by avoiding directly to contract with moist environment.
