二氧化钛 (TiO₂) - 高纯度白色颜料

Wholesale Titanium Dioxide Supplier - TiO2

二氧化钛, 化学式为 TiO₂, is one of the most widely used white pigments in the world. Renowned for its brightness, high refractive index, and superior light-scattering properties, it delivers unmatched opacity and whiteness in products such as paints, plastics, paper, inks, ceramics, and sunscreens.

卡文资源 offers bulk-grade titanium dioxide (Rutile and Anatase grades) tailored for both industrial and food-grade applications. Our TiO₂ is produced using chloride and sulfate processes, ensuring optimal particle size, purity, and dispersion. With global compliance and export capabilities, we are a trusted source for wholesale buyers and manufacturers worldwide. Bulk Titanium Dioxide (TiO₂)

⚙️ 生产方式

1. Sulfate Process

• Involves reacting ilmenite or titanium slag with sulfuric acid.

• The product is then filtered, hydrolyzed, and calcined.

2. Chloride Process

• Uses high-purity rutile or synthetic rutile.

• Titanium tetrachloride (TiCl₄) is oxidized at high temperatures to form TiO₂.

• Preferred for high-purity, low-impurity output.
