High Purity CaS Calcium Sulfide Powder CAS 20548-54-3

Calcium Sulfide is a high-purity inorganic compound with a white to reddish-brown crystalline appearance, known for its semiconductor properties and hygroscopic nature. It exhibits exceptional thermal stability (melting point: ~2000°C) and is widely used in industrial processes, chemical synthesis, and optoelectronic applications 12.

  • High Purity: Available in high - purity grades, typically 99% or higher. High purity is crucial as impurities can disrupt its performance in various applications.
  • Crystal Structure: It crystallizes in a cubic rock - salt structure. This lattice arrangement contributes to its stability and influences properties such as hardness, electrical conductivity, and thermal conductivity.
  • Appearance: Usually appears as a white to yellowish - white powder.
