Product Description

Product Description

1. Definition

Calcium sulfate (CaSO4) is a calcium salt of sulfuric acid. It exists in anhydrous form and as hydrates, with common forms including gypsum (CaSO4·2H2O) and plaster of Paris (CaSO4·0.5H2O). These forms are widely used in various industries due to their unique physical and chemical properties.

2. Production Methods

• Natural Mining: Extracted from gypsum or anhydrite deposits.

• Chemical Reaction: Formed by reacting calcium hydroxide or calcium carbonate with sulfuric acid (H2SO4). For example, Ca(OH)2 + H2SO4 → CaSO4 + 2H2O. It can also be a by-product in phosphate fertilizer production and flue gas desulfurization processes.

3. Storage

Calcium sulfate should be stored in a cool, dry place away from moisture to prevent hydration changes. Keep containers tightly closed to avoid contamination from reactive substances and ensure product stability.

4. Market Information

The global calcium sulfate market is driven by demand from construction, agriculture, and food industries. Key producers are in regions with abundant natural deposits. Prices vary based on purity and form, with higher-purity grades commanding premium prices.

5. Downstream Industries

• Construction: Used in drywall, plaster, and cement additives.

• Agriculture: As a soil conditioner to improve soil structure and supply calcium and sulfur.

• Food: Serves as a dough conditioner, firming agent, and anticaking agent.

Application

Construction Industry
In construction, calcium sulfate is a key ingredient. Gypsum, a hydrate form, is widely used to manufacture drywall panels. These panels are lightweight, fire-resistant, and easy to install, making them popular for interior walls and ceilings. Additionally, plaster of Paris, another form, is used for creating molds, decorative plasterwork, and as an additive in cement to control the setting time, enhancing the workability and strength of concrete.
Agriculture
Calcium sulfate benefits agriculture significantly. It acts as a soil conditioner, improving soil structure by breaking up compacted clay soils and increasing water infiltration. By supplying calcium and sulfur, essential nutrients for plant growth, it helps enhance crop yields. Moreover, it can reduce soil salinity, making it suitable for growing a wider range of crops.
Food Industry
In food production, calcium sulfate serves multiple functions. As a dough conditioner, it strengthens gluten, improving the texture and elasticity of bread and other baked goods. It also functions as a firming agent, helping to maintain the shape of canned vegetables and fruits. Additionally, it acts as an anticaking agent in powdered foods, preventing clumping and ensuring a free - flowing consistency.
Industrial Applications
In industrial settings, calcium sulfate is used in the production of pigments, paper coatings, and as a filler in plastics and rubber products. Its fine particle size and inert nature make it suitable for enhancing the properties of these materials, such as improving opacity in paper and adding bulk to plastics.
