2. Physical and Chemical Properties
Physical Indicators
- Appearance: Uniform white fine powder
- Odor: Odorless
- Solubility: Insoluble in water, ethanol, organic solvents; soluble in hot concentrated sulfuric acid, hydrofluoric acid; insoluble in weak acid and alkaline solution at room temperature
- Melting Point: 1840 °C
- Density (20 °C): 4.2–4.3 g/cm3 (Rutile); 3.8–3.9 g/cm3 (Anatase)
- Refractive Index: Rutile 2.76, Anatase 2.55
- Hygroscopicity: Slightly hygroscopic under high humidity air
- Aqueous Stability: Stable in neutral, weak acid and weak alkaline aqueous systems, no hydrolysis reaction
Chemical Characteristics
- Molecular Structure: Ionic inorganic oxide crystal, two main crystal forms: rutile and anatase
- Core Functional Mechanism: High hiding power white pigment with excellent UV scattering capacity; physical UV reflector for sunscreen; stable inorganic filler to improve covering, whitening and weather resistance of coatings, plastics and rubber
- Photostability: Rutile type has good light stability; anatase type has photocatalytic activity under UV irradiation, easy to cause resin aging
- Thermal Stability: Ultra-high thermal stability, no decomposition below 1600 °C
- Chemical Compatibility: Compatible with most polymer resins, cosmetic oils and water-based coating systems; reacts with concentrated strong acid under heating; incompatible with strong reducing agents at high temperature
3. Main Application Fields
- Core Application: Coating & Paint White Pigment
Main whitening covering pigment for architectural coatings, industrial anti-corrosion paint, automotive paint and printing ink, improving weather resistance and hiding power - Cosmetic Physical Sunscreen Raw Material
Physical UV scattering agent covering UVA+UVB for sunscreen cream, foundation, BB cream and baby sun care products - Plastic & Rubber Filler
Whitening brightening additive for PVC, PE, PP, masterbatch and silicone rubber to enhance surface gloss and anti-aging performance - Food & Pharmaceutical Additive
White colorant for candy, tablet coating and oral capsule shell (food/pharma grade with strict heavy metal control) - Paper & Textile Auxiliary
Filler for coated paper, synthetic fiber delustering agent to increase paper whiteness and fabric matte effect
4. Platform Category & Product Group Guidance
1) Domestic B2B Platform Category
Recommended Path: Inorganic Chemicals / Pigment & Functional Fillers
Reason: Multi-purpose inorganic white oxide pigment widely used in coating, plastic, cosmetic and food industries
2) English Product Group Dropdown Options
