Types of CASO4 Gypsum

While CASO4 gypsum primarily refers to the anhydrous form of calcium sulfate, understanding the broader context of calcium sulfate minerals is useful, as they are often processed or referred to together in industrial supply chains. The distinctions lie mainly in their hydration levels and manufacturing processes, leading to different properties and applications.

The primary classifications of calcium sulfate minerals relevant to industrial use are anhydrous (CASO4), hemihydrate (CaSO4·½H2O), and dihydrate (CaSO4·2H2O).

• Type 1: CASO4 Gypsum (Anhydrite/Calcium Sulfate Anhydrous): This is the water-free form. It occurs naturally as the mineral anhydrite or is produced by heating gypsum dihydrate to temperatures above 100°C, driving off all its water molecules. It is harder and denser than gypsum dihydrate. Its low water absorption and high-temperature resistance make it ideal for specialized plasters, cement additives, and certain industrial molding compounds. In Dortmund, manufacturers requiring materials that can withstand extreme conditions or prolonged moisture exposure often turn to this form.
• Type 2: Gypsum Hemihydrate (Plaster of Paris/CaSO4·½H2O): This form contains half a molecule of water per molecule of calcium sulfate. It is produced by heating gypsum dihydrate to controlled temperatures, typically between 100°C and 150°C, removing only some of its water content. When mixed with water, it rehydrates and sets rapidly into a hard mass, making it highly suitable for casting, dental molds, and fast-setting construction plasters.
• Type 3: Gypsum Dihydrate (Gypsum/CaSO4·2H2O): This is the most common form, naturally occurring as gypsum rock. It contains two molecules of water per molecule of calcium sulfate. It is the raw material from which hemihydrate and anhydrous forms are often derived through controlled heating. Gypsum dihydrate itself is used in agriculture to improve soil structure and as a component in cement production to control setting times. Manufacturers in sectors utilizing cement or soil conditioners might source this directly.
• Type 4: Industrial Grade CASO4 Gypsum: This category refers to CASO4 gypsum that meets specific industrial standards but may not be of the same purity or fineness as materials used in artistic or medical applications. Its composition is optimized for bulk industrial use, such as in cement manufacturing, as a filler, or in chemical processes. Sourcing industrial grade CASO4 gypsum from reliable suppliers like Maiyam Group ensures consistency for large-scale operations in regions like Dortmund.

For industrial manufacturers in Dortmund, Germany, the choice between these types depends heavily on the specific application. CASO4 gypsum (anhydrous) offers superior performance in demanding environments, while hemihydrate provides rapid setting capabilities. Dihydrate is fundamental for cement and agriculture, and industrial grades ensure cost-effectiveness for bulk applications. Understanding these differences is crucial for selecting the optimal CASO4 gypsum product for your manufacturing needs in 2026.
