Liquid Calcium Chloride
July 11th, 2010 by samfrea

Calcium Chloride is a bulk chemical commodity used in all kinds of industries. Worldwide production capability is in the region of 3.5 Million Tonnes per annum. Demand can vary considerably depending on the severity of winter situations in North America and northern Europe, however usually is in the area of 2.5 Million Tonnes per annum.


Calcium Chloride is produced in a lot of completely different varieties, relying on the application. Probably the most widely used products embrace:-

o Anhydrous

o Flake

o Dihydrate

o Hexahydrate

o Liquid

Each of the above kinds is moreover out there in several grades from technical grades for industrial purposes, to excessive purity food and pharmaceutical grades. As well as, different types are available corresponding to powder, prill, pellet and briquette - once more depending on the application.


Calcium Chloride is used widely as a desiccant/deliquescent. A desiccant is any materials which has a high affinity for water. A deliquescent also has a high affinity for water but absorbs water to such an extent that it eventually dissolves and turns to a liquid. Sometimes called a desiccant however is more precisely described as a deliquescent as it'll finally turn to liquid if it absorbs sufficient moisture. Because it absorbs water, it types hydrated forms of Calcium Chloride. There are at the very least four levels of hydration - 1, 2, 4 and 6-Hydrate. As water is absorbed, the hydration stage increases until, depending on temperature, the Calcium Chloride will dissolve and turn into a highly concentrated liquid. Liquid Calcium Chloride has its personal helpful properties together with a excessive specific gravity and very low freezing factors - as low as -50oC to -60oC - which allows it for use in cooling and de-icing applications.


Calcium Chloride (CaCl2) is a bulk chemical broadly used all through industry, for quite a few applications. It is used as a source of Calcium, in industrial processes and water remedy, as a meals additive (E509) as a sequestrant or firming agent. It is usually used as an accelerant within the setting of concrete and liquid Calcium Chloride can be used for tyre weighting in agricultural vehicles.

However, the majority of its applications make use of its desiccant/deliquescent properties which make it a cost-effective drying agent and suited to producing extremely concentrated options with low melting/freezing points. It is used for de-icing functions, significantly on roads where it absorbs water and forms options with freezing factors a lot lower than that of water, thus stopping formation of ice. The absorption of water by Calcium Chloride is exothermic which accelerates the melting of any ice already formed. Calcium Chloride is widely used as a desiccant for drying industrial gases and liquid hydrocarbons (propane, butane).

Calcium Chloride can also be used in the Oil and Fuel business, as an additive to completion fluids where it is used to increase density, and as an additive to drilling muds.

Sometimes liquid calcium chloride is also used in fertilizers. Ward Chemical is the top manufacturer of natural fertilizers containing this compound. They say that this biodegradable additive neutralizes the pH balance of the soil, reduces crusting, assists plant progress, ensures water retention, reduces excessive alkaline/sodium/magnesium/saline content material, and protects plants from disease. Working rapidly and effectively, agriculture is one of many makes use of for this nice mineral compound.
