3. Manufacturing Process: From Raw Material to High Purity Rutile Titania TiO2 for Papermaking
Ilmenite/Titanium Slag → Chlorination / Sulfate Leaching → Purification → Hydrolysis / Calcination → Milling (CNC grinding) → Surface Coating (SiO2, Al2O3) → Testing (ISO/ANSI) → Packing & Delivery
Process Details:
  • Raw Material: Select ilmenite/titanium slag with Fe2O3<13%, TiO2>50%.
  • Chloride / Sulfate Route: China titania tio2 factories started shifting to eco-friendly chloride process for higher purity, lower SO2 emissions, and energy efficiency.
  • Hydrolysis/Calcination: Controlled thermal hydrolysis generates fine, uniform rutile crystals; calcination enhances pigment stability & opacity.
  • Precision Milling & Surface Coating: CNC grinding for particle uniformity; in-situ SiO2-Al2O3 organic/inorganic coating upgrades dispersion and anti-yellowing performance.
  • Quality Inspection: Full QC per ISO 591/ASTM D476 with spectral colorimetry, fineness, oil absorption, dispersibility, and heavy metal benchmarks.

8. Expert FAQ: Titania TiO2 Properties & Applications
Q1: What is the basic composition of rutile titania tio2 and its advantage over anatase?
Rutile titania (TiO2) features a tetragonal crystal structure, higher refractive index (n=2.7), superior weather resistance, UV stability, and opacity—making it ideal for exterior and papermaking applications.
Q2: What specific standards do major titania tio2 manufacturers comply with for papermaking usage?
Key certifications include ISO 591 (global grades), FDA §176.170/180 (food contact safety), REACH, and EN/ANSI protocols for heavy metal and migration limits.
Q3: What is meant by “oil absorption” in TiO2 technical data?
Oil absorption (g/100g) reflects the TiO2 powder’s surface area and ease of dispersion in organic media. Lower values indicate better processability and less binder demand in coatings/paper.
Q4: Can titania tio2 be used in recycled papermaking systems?
Yes, high-dispersion rutile TiO2 grades are optimized for recycled fiber systems, maintaining brightness and filler retention across multiple paper-lifecycle uses.
Q5: What particle size is optimal for high-opacity paper grades?
Recommended D50 is 0.26–0.32μm. CQTiO2's rutile papermaking grade delivers >96 brightness and minimal residue at this size, ensuring best print results.
Q6: How long is the delivery/lead time for bulk or custom orders?
Typical ex-works time: 7–14 days for standard grades, 18–25 days for custom coatings or packaging, with full traceability and COA.
