Basic Information and Parameters<\/h2>\n<p>Calcium sulfide, with the CAS number 20548-54-3, is an inorganic compound. Its chemical formula is CaS. Calcium sulfide usually appears as a white to light yellow solid powder. It has a molar mass of approximately 72.143 g\/mol. In terms of its physical properties, calcium sulfide is soluble in water and reacts with water to form calcium hydroxide and hydrogen sulfide gas. It has a relatively high melting point, around 2,000 \u00b0C.<\/p>\n<p>The purity of our factory - supplied calcium sulfide is carefully controlled to meet high - quality standards. We offer it at a good price, which makes it a cost - effective choice for various industries. The particle size of the calcium sulfide powder can be adjusted according to different customer requirements, ensuring its suitability for different applications.<\/p>\n<h2 id=\"uses\">2. Product Uses<\/h2>\n<p>Calcium sulfide has a wide range of applications in different fields. In the chemical industry, it is used as a raw material for the production of other sulfur - containing compounds. For example, it can be used to synthesize calcium polysulfide, which is widely used in the treatment of heavy metal wastewater due to its strong chelating ability with heavy metal ions.<\/p>\n<p>In the field of luminescent materials, calcium sulfide is an important matrix material. When doped with certain rare - earth elements such as europium (Eu) or cerium (Ce), it can exhibit excellent luminescent properties. These luminescent materials are used in lighting devices, display screens, and even in some special decorative applications.<\/p>\n<p>In agriculture, calcium sulfide can be used as a soil conditioner. It can adjust the soil pH value, improve soil structure, and provide necessary calcium and sulfur elements for plant growth. This helps to enhance crop yield and quality.<\/p>\n<h2 id=\"usage\">3. Product Usage<\/h2>\n<p>When using calcium sulfide in the chemical synthesis process, it is necessary to pay attention to the reaction conditions. For example, in the synthesis of calcium polysulfide, calcium sulfide should be slowly added to an appropriate amount of sulfur solution under stirring conditions, and the reaction temperature should be strictly controlled within a certain range to ensure the quality of the product.<\/p>\n<p>For the preparation of luminescent materials, the doping process of rare - earth elements needs to be precisely controlled. First, calcium sulfide powder and rare - earth element compounds are mixed in a certain proportion, and then sintered at a high temperature in a reducing atmosphere to obtain the desired luminescent material.<\/p>\n<p>When using calcium sulfide as a soil conditioner, it should be evenly spread on the soil surface and then plowed into the soil. The dosage should be determined according to the soil type, soil pH value, and crop requirements.<\/p>\n<h2 id=\"case-studies\">4. Product Use Case Studies<\/h2>\n<p>Case 1: Chemical Synthesis<br \/>\n    A chemical company was engaged in the production of calcium polysulfide for heavy metal wastewater treatment. They purchased our calcium sulfide and followed our recommended reaction conditions. By adding calcium sulfide to a sulfur solution at a temperature of 80 - 90 \u00b0C and continuously stirring for 2 - 3 hours, they successfully synthesized high - quality calcium polysulfide. After using this calcium polysulfide in the treatment of heavy metal wastewater, the removal rate of heavy metal ions such as lead, cadmium, and mercury reached over 95%, effectively meeting the environmental protection requirements.<\/p>\n<p>Case 2: Luminescent Material Production<br \/>\n    A lighting materials manufacturer used our calcium sulfide to produce Eu - doped calcium sulfide luminescent materials. They mixed calcium sulfide with europium oxide in a molar ratio of 100:1, and then sintered the mixture at 1200 \u00b0C in a hydrogen - nitrogen reducing atmosphere for 4 hours. The obtained luminescent material had a high luminous efficiency and a long afterglow time. It was used in the production of energy - saving LED lights, which significantly improved the lighting effect and energy - saving performance of the products.<\/p>\n<p>Case 3: Agriculture<br \/>\n    A large - scale farm used our calcium sulfide as a soil conditioner. They applied calcium sulfide at a rate of 50 kg per mu to acidic soil. After one growing season, the soil pH value increased from about 5.0 to 6.5, and the soil structure was significantly improved. The crops on this farm, such as corn and wheat, showed better growth vigor.
