Understanding Lithopone 1345-05-7: Composition and Industrial Relevance

Lithopone 1345-05-7 represents a hybrid inorganic pigment composed of barium sulfate and zinc sulfide in varying ratios. This compound occupies a unique position in industrial applications due to its dual-function characteristics as both a pigment and filler. Chemical stability manifests through its resistance to solvents, alkalis, and UV degradation, making it indispensable for outdoor applications. Production volumes exceed 350,000 metric tons globally, driven primarily by construction materials (42%), polymer manufacturing (31%), and coatings industries (27%). The CAS registry 1345-05-7 specifically denotes the optimized 30% ZnS/70% BaSO4 formulation that delivers maximum reflectance at 97.5% across visible spectrum wavelengths.

Technical Performance Parameters and Functional Advantages

Premium-grade lithopone exhibits distinctive optical properties with a refractive index of 1.84 and brightness values exceeding 98% on the ISO 2470 scale. Technical advantages stem from its crystalline structure where zinc sulfide particles (0.3-0.5μm) disperse within barium sulfate matrices, creating light-scattering efficiency unmatched by alternatives like titanium dioxide. Field testing confirms a 45% increase in dispersion homogeneity compared to standalone zinc sulfide and 23% higher UV resistance versus competitive composites. Economically, it delivers 68% cost efficiency relative to titanium dioxide while achieving 80-92% opacity coverage in film applications. Performance metrics significantly outperform industrial minimums with 99.2% chemical purity and moisture content below 0.3%.

Global Manufacturing Methodologies and Production Standards

Industrial-scale synthesis occurs through precisely controlled precipitation reactions between zinc sulfate and barium sulfide solutions under alkaline conditions at 60-80°C. Leading lithopone 1345-05-7
manufacturer facilities implement continuous process reactors that ensure particle size distribution consistency within ±2.5% tolerance. Quality certification requirements include ISO 9001:2015 compliance, REACH registration, and batch-specific analysis verifying toxic heavy metals below 30ppm. Production analytics reveal China dominates global output with 78% market share, followed by European producers (15%) and North American manufacturers (7%). Monthly capacities average 8,500 tons per major production facility, with advanced plants achieving 99.8% raw material utilization through closed-loop systems.
