Titania TiO2 (titanium dioxide, TiO₂) is a white, inorganic pigment with unparalleled opacity, brightness, and UV resistance. Leveraging a unique crystal lattice structure (rutile or anatase), it leads the market for color, durability, and performance in:

• Building additives for colorful and plaster materials
• Coatings, plastics, inks, paper, ceramics, and water treatment industries
• Specialty applications: photocatalysis, solar cells, environmental remediation

As of 2023, global titania tio2 demand reached about 6.4 million tonnes/year (Statista), with China contributing over 47% of world output, and home to leading titania tio2 factories and suppliers.

Manufacturing Process

1. Raw Material Selection: Natural ilmenite (FeTiO3), rutile sands, or synthetic precursors are sourced for optimal TiO₂ yield.
2. Sulfate or Chloride Process:
   • Sulfate process: TiO₂ is precipitated from titanium sulfate using concentrated sulfuric acid, leading to higher impurity removal but more waste.
   • Chloride process: Raw material reacts with chlorine gas at 900°C; titanium tetrachloride (TiCl₄) is then oxidized to ultra-pure TiO₂, yielding finer pigments and being more eco-friendly (Source: ScienceDirect).
3. Calcination & Milling: Fine-tuning of particle size, crystallinity (rutile/anatase ratio) for best opacity and dispersibility.
4. Surface Treatment: Silica, alumina, zirconia coating for weatherability, gloss, anti-yellowing — vital for building/plaster mixes.
5. Quality Control & Packing: Each batch is ISO 591, ANSI A208 certified; filtration, micronization, packaging to prevent contamination.

Leading titania tio2 manufacturers in China utilize advanced DCS/PLC automation, real-time spectral analysis (for L* brightness and b* undertone), and environmental recovery units to meet global EHSS requirements.

Schematic: Key steps in titania tio2 production (Chloride route shown)

• Exceptional Whiteness & Brightness (L* >96): Enables pure color and masking in both colorful plaster and wall putty formulations.
• Acid & Alkali Stability: Maintains pigment integrity even in strong cementitious matrices, surpassing most organic alternatives.
• Surface-Treated, Enhanced Dispersion: Hydrophobic coatings enable quick wetting and minimal agglomeration in water-based or solvent mixes.
• Weather & UV Resistance: High rutile content confers outstanding outdoor durability, essential for lasting building facades.
• Low Oil Absorption: Ensures consistent viscosity and processability in pre-mixed construction compounds.
• Compliance with Global Standards: Each batch meets ISO 591, REACH, ANSI A208 protocols and is tested for hazardous substances.

• Crystal Control: Select between rutile (for maximum opacity and UV stability) and anatase (for enhanced whiteness in interiors).
• Surface Modification: Detailed custom silica/alumina treatments to suit different binder systems (e.g., acrylic, silicone, gypsum, polymer renders).
• Particle Size Distribution: Flexible D90 tailoring for high-gloss vs matt plaster or anti-settling properties.
• Color Metrics (L*, b*, a*): Batch-customized to meet project-specific undertones and lightfastness needs.
• Dedicated Blends & Packing: Options for waterborne, solventborne, and cementitious system pre-packs, FFS or 1 MT bag shipping.
