Calcium Chloride Flakes, Pellets, Powder and Brine

What Is Calcium Chloride?

Calcium Chloride is a highly water-soluble inorganic calcium salt supplied as flakes, pellets, powder, granules or liquid brine.

It is hygroscopic and deliquescent, meaning that it readily absorbs moisture from the surrounding air. Dissolving solid calcium chloride in water releases heat, while the resulting brine has a lower freezing point than water.

These properties make calcium chloride useful in deicing, dust control, moisture absorption, industrial brines, water treatment and other applications.

Calcium Chloride Product Information

Commercial flakes are not always pure dihydrate, and high-strength solids are not always completely water-free. The guaranteed CaCl₂ content and test basis should be stated in the specification.

Which Calcium Chloride Form Should Buyers Select?

These are typical commercial ranges rather than guaranteed AOZUN specifications. Exact concentration, hydration state and physical form must be confirmed for each grade.

Which Calcium Chloride Specifications Matter?

The COA should identify whether results are reported on an as-is, dry or active-ingredient basis.

Where Is Calcium Chloride Used?

Deicing and Dust Control

Calcium chloride absorbs moisture, forms brine and depresses the freezing point of water. Suitable grades are used for road deicing, anti-icing and dust control on unpaved surfaces.

Application rates must reflect local conditions and environmental requirements.

Industrial Brines

Calcium chloride solutions are used as secondary cooling fluids, process brines and density-adjustment fluids. Buyers should compare concentration, density, clarity, corrosion control and operating temperature.

Oil and Gas

Selected grades are used in drilling, completion and workover fluids where a clear, weighted brine is required. Oilfield use requires the correct density and impurity specification.

Concrete and Construction

Calcium chloride may accelerate the setting and early strength development of concrete. Its use is restricted or prohibited in some reinforced, prestressed or corrosion-sensitive concrete applications.

The applicable building code and chloride limit must be checked before use.

Water Treatment

Calcium chloride may supply calcium ions, support selected precipitation processes or assist certain wastewater-treatment operations. Suitability depends on the water chemistry and treatment objective.

Food Processing

Food-grade calcium chloride is identified as INS/E509 and may serve as a firming agent, stabilizer or other permitted processing ingredient.

Only an approved food-grade product meeting the destination market’s purity requirements should be used in food. Industrial and deicing grades are not food grade.

Why Does Calcium Chloride Become Wet or Form Lumps?

Calcium chloride readily absorbs moisture from air. If the packaging is opened, damaged or poorly sealed, the material may cake, form lumps or eventually produce liquid brine.

This does not mean every lumped product has chemically decomposed, but it may affect:

• Accurate dosing

• Product flow

• Spreading performance

• Active concentration

• Storage and handling

Moisture-resistant packaging and careful warehouse control are therefore essential.

Packaging, Storage and Safe Handling

Solid calcium chloride is commonly supplied in moisture-resistant bags, drums or FIBCs. Liquid grades may be delivered in drums, IBCs, tank trucks or other compatible bulk containers.

Store the product:

• In tightly sealed original packaging

• In a dry, covered and ventilated location

• Away from moisture and incompatible materials

• On protected pallets rather than directly on the floor

• In corrosion-resistant equipment when stored as brine

Calcium chloride can cause serious eye irritation. Its dissolution in water is exothermic, so add solid product gradually to water under controlled agitation. Do not add water rapidly to a large concentrated mass of solid calcium chloride.

Wear suitable gloves and eye protection and consult the current Safety Data Sheet.

Why Source Calcium Chloride from AOZUN?

AOZUN can support buyers with:

• Flake, pellet, powder and liquid options

• Industrial, food and application-specific grade matching

• Specification, COA and SDS support

• Moisture-resistant packaging

• Sample evaluation

• Export and logistics coordination

• Pre-shipment quality verification

Grade availability, certification and guaranteed specifications should be confirmed for every order.

Calcium Chloride FAQ

Is calcium chloride organic or inorganic?

Calcium chloride is an inorganic salt composed of calcium and chloride ions.

Is anhydrous calcium chloride the same as calcium chloride dihydrate?

No. They have different water contents, CAS numbers and molecular weights. Their effective CaCl₂ contribution per kilogram is also different.

Is 77% calcium chloride anhydrous?

Usually not. Products around 74–77% are commonly associated with the dihydrate-rich form. Buyers should verify the specification rather than relying only on appearance.

Can industrial calcium chloride be used in food?

No. Food applications require a food-grade product that complies with the applicable food-additive standard and impurity limits.

Does calcium chloride release heat in water?

Yes. Dissolution is exothermic. Solid calcium chloride should be added gradually to water with suitable agitation and temperature control.
