Lithopone, a historic white pigment, is a mixture of zinc sulfide (ZnS) and barium sulfate (BaSO₄). Understanding its chemical formula and sourcing reliable suppliers is crucial for various industrial applications. This article delves into the composition, applications, and considerations when choosing a lithopone supplier, with a focus on quality and consistency. We will also cover the key properties and benefits of using lithopone in different industries.

The chemical formula of lithopone isn't a single compound but a blend. It typically consists of approximately 30% zinc sulfide (ZnS) and 70% barium sulfate (BaSO₄). The ZnS component provides the opacity and whiteness, while BaSO₄ contributes to its inertness and improves its dispersion properties. The ratio can vary slightly depending on the intended application and the supplier's specifications. The production process involves reacting zinc sulfide and barium sulfate under controlled conditions to achieve a homogenous mixture. This careful blending is essential for maintaining consistent quality and performance.
Key Takeaway: Lithopone’s efficacy relies on the precise ratio of zinc sulfide and barium sulfate, highlighting the need for stringent quality control during production.
Lithopone finds applications in various industries due to its cost-effectiveness and opacity. It's widely used as a white pigment in paints, plastics, paper coatings, and rubber. Specifically, it's popular in applications where high whiteness isn’t paramount but a good balance of properties is required. While it has been largely replaced by titanium dioxide in many applications due to TiO₂'s superior brightness and hiding power, lithopone remains a viable option for certain cost-sensitive applications. It's also used in some printing inks and as a filler in certain materials.
Key Application Areas:
• Paints and Coatings
• Plastics
• Paper Coatings
• Rubber Industry
Selecting a reliable lithopone supplier is critical for maintaining product quality and consistency. Consider factors such as the supplier's reputation, production capacity, quality control procedures, and ability to meet your specific requirements. A reputable supplier will provide detailed specifications for their lithopone, including the exact ratio of ZnS to BaSO₄, particle size distribution, whiteness index, and other relevant parameters. Look for suppliers with certifications demonstrating adherence to international quality standards. CQ Titanium Dioxide is a trusted supplier offering consistent, high-quality lithopone.
While both lithopone and titanium dioxide (TiO₂) are white pigments, TiO₂ generally offers superior performance characteristics. TiO₂ boasts higher brightness, hiding power, and UV resistance. However, TiO₂ is typically more expensive than lithopone. The choice between the two depends on the specific application and budget constraints. Lithopone remains a cost-effective alternative for applications where extremely high whiteness isn’t crucial. Consider the long-term cost-benefit analysis when selecting a pigment.
