Calcium sulfate (CaO4S) is a granular, white powder derived from natural sources. With a molecular weight of 136.14 g/mol, it features a density of 2.96 g/cm³, which enables it to settle well in soil amendments. This product has a melting point of 1450 °C and is slightly soluble in water at 0.3%, making it suitable for soil applications where moisture retention and nutrient delivery are essential. When purchasing, consideration should be given to its density, purity, and moisture content, typically observed at 5% maximum. When ordering, specify the pack size (50 kg) and any desired documentation to ensure proper usage in specific applications.
Delivery

Frequently asked questions
What is the CAS number of Calcium Sulfate?
The CAS registry number for Calcium Sulfate is 7778-18-9. Its chemical formula is CaO4S, with a molecular weight of 136.14 g/mol. Quote this number when requesting a quotation or checking documentation, as it identifies the substance unambiguously regardless of the trade name used.
What are the other names for Calcium Sulfate?
Calcium Sulfate is also referred to as CALCIUM SULFATE, Anhydrous gypsum, Drierite, Karstenite, Muriacite and Basic calcium sulfate. These names describe the same substance, so a specification or enquiry written against any of them can be matched to this product.
What grade of Calcium Sulfate is supplied?
Calcium Sulfate is supplied as Technical grade. State the grade your process requires when requesting a quotation — where an alternative grade can be sourced, it is confirmed at quotation stage rather than assumed.
What concentration is Calcium Sulfate supplied at?
Calcium Sulfate is supplied at a concentration of 17.5% S MIN. Concentration and assay are separate figures: the concentration describes the strength of the material as supplied, and the certificate of analysis issued for your consignment carries the measured values for that batch.
What does Calcium Sulfate look like?
Calcium Sulfate is described as granular, white powder. Appearance is a useful first check on receipt of goods, though it does not replace the certificate of analysis for confirming that the material meets specification.
What is Calcium Sulfate used for?
Common applications include soil conditioning — Improves soil structure and enhances moisture retention., plaster and cement production — Acts as a setting agent in construction materials., plant growth enhancers — Provides calcium and sulfur, essential nutrients for crops., desiccant in packaging — Ensures moisture control in sensitive products. and food processing — Used in certain food preservation techniques as a firming agent.. The suitability of the product for a particular process depends on the grade and specification required, which is worth confirming against your own process conditions.
