- Calcium hydroxide, also
known as slaked lime, is a chemical compound with the chemical formula
Ca(OH)2. It is a colourless crystal or white powder, and is obtained
when calcium oxide (called lime or quicklime) is slaked with water.
- Calcium hydroxide
occurs as white and odourless crystals or powder. It causes high pH in a
water solution (>12 in a saturated solution). The substance is stable
under ordinary conditions of use and storage but absorbs readily carbon
dioxide from air to form calcium carbonate.
- Calcium hydroxide is
one of the chemical compounds that are not associated in calcium
supplement manufacturing because of the presence of acidic properties.
It takes the form of either white powder or colorless crystal which is
produced when another chemical compound which is the calcium oxide is
quenched with water.
- Calcium hydroxide is
refined from limestone. The first step is by heating limestone to form
calcium oxide. The second step is by reacting the calcium oxide with
water which forms calcium hydroxide and heat. This hydration reaction
breaks the calcium oxide down into fine particles of calcium hydroxide,
also called “hydrated lime”. The sizing of the calcium hydroxide is
further modified by milling the product to ensure consistency.
- Calcium hydroxide is
applied into a wide variety of chemical and food industry applications.
The dominating uses are as a pH-regulating agent and raw material for
mortar. The substance is also used as an additive in cement.
- Calcium oxide or
calcium hydroxide is used as liming materials for agricultural use,
particularly when a rapid change in pH is desired. Calcium hydroxide is
the second most effective of commonly used liming materials, with a
neutralizing value (calcium carbonate equivalent-CCE) of 136% for the
pure material.
- Hydrated lime is
valuable in many industrial applications, including waste and water
treatment, the drying and stabilization of soil, Ph and odor control,
agricultural applications, asphalt modification and building product
components such as plasters and whitewash. It is also frequently used in
the scrubbing of sulfur dioxide from stack gases emitted from industrial
boilers and power plants.
- Calcium hydroxide
products are used in a variety of water treatment systems. The substance
is used for softening, pH control and impurity removal in potable water
systems. It is also used as a neutralizing agent and precipitant in
industrial and municipal waste water applications.
- Other industrial uses
are as performance additive and functional filler in rubber and plastic
applications. In rubber production it acts as an accelerator.
- Calcium hydroxide is
important for the production of sugar from sugar cane or sugar beets.
The substance raises the pH of the raw juice and reacts with impurities
to form insoluble calcium organic compounds that can be removed.
- The demand of hydrated
lime is estimated at around 9000 tonne per annum. While there are a
number of lime kilns in the Assam- Meghalaya belt, most of these units
are confining themselves to production of quick lime for supply to paper
mills.The installed capacity of hydrated lime plant in this region is
about 4500 tonne per annum, considering this 50% shortfall, if a tiny
unit produce 800 tonne per annum, there is a scope for 5/6 units in this
region.
- More than 90% of the
lime (burned or hydrated) produced in the United States is used for
basic or industrial chemistry. The primary use is for steel manufacture
(30%), metallurgy, air pollution control and water and sewage wastewater
treatment (24%), cement and mortar, chemical manufacture, manufacture of
glass and paper, diluents and carriers of pesticides such as lime-sulfur
and Bordeaux mixture, bleach production, and other chemical
manufacture
