APPLICATIONS OF CALCIUM CHLORIDE
Marine Aquarium Use:
- In marine aquariums, calcium chloride is added to introduce bioavailable calcium for calcium carbonate-shelled animals such as mollusks and cnidarians.
- Calcium hydroxide (kalkwasser mix) or a calcium reactor can also be used to introduce calcium, however calcium chloride addition is the fastest method and has minimal impact on pH.
Desiccant:
- Drying tubes are frequently packed with calcium chloride.
- Kelp is dried with calcium chloride for use producing sodium carbonate.
- Adding solid calcium chloride to liquids can remove dissolved water.
- Calcium chloride is also used in products such as DampRid and Dri-Z-Air which is advertised as an air moisture absorber.
- These hygroscopic properties are also applied to keep a liquid layer on the surface of the roadway, which holds dust down.
Freezing Point Depression:
- By depressing the freezing point, calcium chloride is used to usually prevent ice formation and to deice.
- This is particularly useful on road surfaces.
- Calcium chloride dissolution is exothermic, and is relatively harmless to plants and soil; however, recent observations in Washington state suggest it may be particularly harsh on roadside evergreen trees.
- It is also more effective at lower temperatures than sodium chloride.
- When distributed for this use, it usually takes the form of small, white balls a few millimetres in diameter, called prills.
- Solutions of calcium chloride can prevent freezing at temperature as low as -52 °C (-62 °F), making it ideal for filling agricultural implement tires as a liquid ballast, aiding traction in cold climates.
Source Of Calcium Ions:
- Calcium chloride is used to increase the hardness in swimming pools and piscines.
- This reduces the erosion of the concrete in the pool.
- By Le Chatelier's principle and the common ion effect, increasing the concentration of calcium in the water will reduce the dissolution of calcium compounds essential to the structure of concrete.
Food:
- As an ingredient, it is listed as a permitted food additive in the European Union for use as a sequestrant and firming agent with the E number E509, and considered as generally recognized as safe (GRAS) by the U.S. Food and Drug Administration.
- The average intake of calcium chloride as food additives has been estimated to be 160–345 mg/day for individuals.
- As a firming agent, calcium chloride is used in canned vegetables, in firming soybean curds into tofu and in producing a caviare substitute from vegetable or fruit juices.
- It is commonly used as an electrolyte in sports drinks and other beverages, including bottled water.
- The extremely salty taste of calcium chloride is used to flavour pickles while not increasing the food's sodium content.
- Calcium chloride's freezing-point depression properties are used to slow the freezing of the caramel in caramel-filled chocolate bars.
Brewing Beer:
- In brewing beer, calcium chloride is sometimes used to correct mineral deficiencies in the brewing water.
- It affects flavour and chemical reactions during the brewing process, and can also affect yeast function during fermentation.
- Calcium chloride is sometimes added to processed milk to restore the natural balance between calcium and protein in casein for the purposes of making cheeses, such as brie, Pelardon and Stilton.
- Also, it is frequently added to sliced apples to maintain texture.
Medicine:
- Calcium chloride can be injected as intravenous therapy for the treatment of hypocalcaemia.
- It can be used for magnesium intoxication.
- Calcium chloride injection may antagonize cardiac toxicity as measured by electrocardiogram.
- It can help to protect the myocardium from dangerously high levels of serum potassium in hyperkalemia.
- Calcium chloride can be used to quickly treat calcium channel blocker toxicity, from the side effects of drugs such as diltiazem (Cardizem) — helping avoid potential heart attacks.
Concrete Mix:
- Calcium chloride is used in concrete mixes to help speed up the initial setting, but chloride ions lead to corrosion of steel rebar, so it should not be used in reinforced concrete.
- Calcium chloride may also be used for this purpose and can provide a measure of the moisture in concrete.
pH buffer:
- Calcium chloride is used in swimming pool water as a pH buffer and to adjust the calcium hardness of the water.
Additives:
- Calcium chloride is included as an additive in plastics and in fire extinguishers, in waste water treatment as a drainage aid, in blast furnaces as an additive to control scaffolding (clumping and adhesion of materials that prevent the furnace charge from descending), and in fabric softener as a thinner.
Heating:
- The exothermic dissolution of calcium chloride is used in self-heating cans and heating pads.
Oil:
- In the oil industry, calcium chloride is used to increase the density of solids-free brines.
- It is also used to provide inhibition of swelling clays in the water phase of invert emulsion drilling fluids.
Industrial Production:
- Acts as Flux material (Decreasing melting point) in Davy process for the industrial production of Sodium metal, through the electrolysis of Molten Sodium Chloride.
Ceramics:
- Calcium chloride is also an ingredient used in ceramic slip ware.
- It suspends clay particles so that they float within the solution making it easier to use in a variety of slip casting techniques.
