Product Usage

Calcium Sulfide is a versatile inorganic compound that holds a significant position in fine chemicals and specialized industries. In the coatings and plastics industry, due to its unique luminescent properties, it is frequently used as a base material for manufacturing fluorescent paints, luminous powders, and glow-in-the-dark plastics. In the metallurgical industry, it acts as an efficient purifying agent for the precipitation and recovery of heavy metals from wastewater, showing remarkable effectiveness in removing mercury and lead. Additionally, it is utilized as a depilatory agent in leather processing and as a raw material for certain pesticides in agriculture. In recent years, with the advancement of material science, its research and application in optoelectronic materials and the semiconductor field have become increasingly widespread.
