Manufacturing Process: 6618 Titanium Dioxide

• Raw Materials: Ilmenite or Rutile ore processed under controlled conditions to guarantee ≥99% purity.
• Digestion: Employing sulfate (hydrometallurgical) or chloride (pyrometallurgical) processes for optimal separation.
• Calcination & Classification: Thermal conversion under strict temperature profiles yields uniform anatase crystals with minimal agglomeration.
• CNC Grinding: Advanced micronizing ensures D₅₀ particle size near 0.22μm, critical for paper opacity.
• Surface Treatment: Optional coating (e.g., Al₂O₃, SiO₂, hydrophilic agents) imbues 6618 titanium dioxide with dispersion and retention performance.
• QC & Certification: Each batch undergoes ISO/GB compliant validation (see specs above), ensuring traceability and repeatable application results.

Key Differentiators: All production steps are executed per ISO 591-1:2000 (TiO₂ standards), enabling stable performance and safety (including low heavy metal content, RoHS, and FDA grade for food contact, where required).
