Description

Calcium sulphide (CaS) is a white to pale yellow cubic crystalline solid, chemically similar to rock salt in structure, with highly ionic bonding between Ca²⁺ and S²⁻ ions.​ Properties It has a high melting point (~2400°C), density of 2.5–2.6 g/cm³, and is sparingly soluble in water (~0.02 g/100 mL), hydrolyzing slowly to release H₂S gas and form Ca(OH)₂ or Ca(SH)₂ in moist air.​ Production CaS forms by carbothermic reduction of calcium sulfate (CaSO₄ + 2C → CaS + 2CO₂) or direct combination of calcium and sulfur at high temperature; it occurs naturally as the mineral oldhamite in meteorites.​ Main uses Known for red phosphorescence (glows after light exposure), it is used in luminous paints, phosphors, and varnishes; also as a flotation agent in ore processing, lubricant additive, and heavy metal precipitant in wastewater treatment.​

Model No. N-CH1526

Laboratory Chemicals

Ferrous borate extra pure is a high-quality iron(II) borate compound (commonly referred to as iron(II) borate or ferrous borate), used predominantly in laboratory and industrial settings for applications that demand high purity standards. It typically appears as a fine, air-sensitive solid and is valued for its chemical stability under controlled conditions. The compound features a high degree of purity, making it especially suitable for analytical work, advanced research, and select industrial processes.​ Product Description for Website Ferrous borate extra pure (Iron(II) borate) is a premium-grade inorganic salt prepared to strict purity standards, ensuring low levels of contaminants and accurate stoichiometry for scientific and technical applications. The product is carefully processed and packaged to maintain its chemical integrity and support reliable results in laboratory analysis and synthesis.​ Synonyms: Iron(II) borate, Ferrous borate Chemical Formula: Fe(BO2)2 (hydrated forms and other stoichiometries possible) Appearance: Pale solid, may be air-sensitive Grade: Extra pure (analytical/research grade) Applications: Used in specialized laboratory analyses, catalyst systems, advanced inorganic synthesis, and as a starting material in certain industrial applications where high purity is critical.​ Key Features High purity and controlled chemical analysis for reliable, reproducible results Packaged with minimal contamination risk and maximum shelf-life Suitable for use in chemical research, formulation, and manufacturing at the analytical level​ Safety & Handling Ferrous borate is generally stable under typical laboratory conditions but should be handled with care as it may be sensitive to atmospheric moisture and air. Use standard personal protective equipment and store in a tightly sealed container in a cool, dry environment.​ This concise description is suitable for use as a base product summary or catalog entry for e-commerce or laboratory supply websites, ensuring clarity for research and procurement professionals.​
