Calcium chloride (Calcium Chloride or CaCl₂) is one of the most important and versatile mineral salts. When produced in pure or nearly pure form (e.g., 94%), its industrial applications become even broader.
In this article, we will first discuss its chemical characteristics, then review its major applications, production notes, and domestic supply, and finally introduce Kloran Company as one of the leading and reputable producers and suppliers.

Main Applications of Calcium Chloride 94%

1. Oil and Drilling Industry:
Used to increase the density of drilling fluids and prevent formation swelling in oil wells.

2. Construction and Concrete:
Acts as a setting accelerator for concrete in cold weather and enhances its early strength.

3. De-icing and Dust Control:
Lowers the freezing point of water, melts snow and ice quickly, and prevents dust formation on roads and mines.

4. Water and Wastewater Treatment:
Used to remove heavy metals and control water hardness.

5. Food Industry:
Applied in cheese production, electrolyte drinks, and for preserving the texture of canned products.

Chemical and Technical Properties of Calcium Chloride 94%

Chemical Formula and Structure

Calcium chloride has the formula CaCl₂ and is usually produced in hydrated or anhydrous forms.

Physical and Chemical Characteristics

Color: White

Form: Crystalline solid, granule, or powder

Highly hygroscopic (strongly absorbs water)

Easily dissolves in water, releasing heat upon dissolution

Significantly lowers the freezing point of water, making it suitable for de-icing

Typically produced and supplied at purities between 94% and 96% for industrial use

Standards and Purity

The “94%” label indicates that the material contains at least 94% pure CaCl₂ with minimal impurities. This grade is preferred for more sensitive industrial applications.

Purchasing Domestic and Export-Grade Calcium Chloride

In Iran, several reputable companies produce and supply calcium chloride. Among them, Kloran Chemical Manufacturing Company (based in Semnan) is one of the best-known brands.

• Kloran is one of the largest producers of chlor-alkali products, including calcium chloride, liquid chlorine, and hydrochloric acid.

• Petrola Group Company is also among the trusted suppliers of this product. Its products are manufactured according to international standards and supplied to domestic and foreign industries such as oil, petrochemical, and construction.

Summary

Calcium chloride 94% is an essential substance in the oil, construction, and water treatment industries. With its high solubility and strong moisture absorption, it has diverse and practical applications.
In Iran, Kloran is recognized as one of the most reliable producers and suppliers of this material.
