Zinc Sulfide, scientifically identified as ZnS and bearing the CAS number 1314-98-3, is an inorganic compound of significant industrial interest. Its chemical structure and inherent properties are the foundation of its widespread applications. The compound is typically manufactured through precipitation processes in aqueous media, allowing for precise control over its purity and particle characteristics, which are crucial for its end-use performance.

The purity level of Zinc Sulfide is a critical specification, with industrial grades often requiring a minimum of ≥99.0%. This high purity is essential for applications where contaminants could adversely affect performance, such as in optical components or sensitive electronic materials. The physical appearance is commonly described as a cubic crystal or a light yellow powder, reflecting its solid-state nature under standard conditions.

Particle size is another vital characteristic, often specified within a range such as 3-5 micrometers. This controlled particle size influences factors like dispersibility, surface area, and reactivity, impacting its effectiveness in various formulations. For instance, in pigment applications, finer particle sizes can lead to better opacity and smoother finishes. Understanding these zinc sulfide properties is key for optimal formulation.

The manufacturing process of Zinc Sulfide, particularly the precipitation method, allows for the co-precipitation of other compounds if desired, leading to mixed pigments like lithopone (a mixture of ZnS and BaSO4). However, for pure Zinc Sulfide applications, stringent control is maintained to ensure minimal impurities. The technical data sheets often detail specifications for water content (≤0.8%), and limits for common metallic impurities like iron, copper, nickel, cadmium, and manganese, ensuring the material meets stringent quality standards.

The chemical stability of Zinc Sulfide is notable, though it can react in acidic mediums. Its storage requirements typically involve keeping it in a dry and ventilated warehouse, away from direct sunlight, fire, and moisture, to maintain its integrity. This ensures that the purchased zinc sulfide maintains its intended properties over time.

The ongoing development in the synthesis of Zinc Sulfide aims to further refine its properties, such as enhancing its luminescence or improving its dispersibility in polymer matrices. Companies that supply Zinc Sulfide often provide detailed technical data and support to help customers select the right grade for their specific needs, reinforcing the importance of buy Zinc Sulfide from reputable sources.

In summary, the chemical properties and manufacturing precision of Zinc Sulfide (CAS 1314-98-3) make it an invaluable material in numerous industries. From its appearance and purity to its controlled particle size and low impurity levels, every specification plays a role in its functionality, particularly in specialized applications like optical filters and industrial coatings.
