Description as well as Uses of Caustic Soda Pearls

Caustic Soda Pearls
Caustic soda pearls (also known as sodium hydroxide, caustic soda, NaOH, sodium hydrate, or Sodagrain) are white spheres of caustic soda with a barely perceptible odour. They are soluble in water, with the liberation of heat, and are stable under standard conditions.

Caustic soda is a strong base and, as this kind of, has many applications inside industries all over the world, both now and inside the past.  It is one of the oldest manmade chemicals with excavations in Egypt presenting samples of it dating from 3000 B.C.


Caustic soda is created all around the earth with world production standing at approximately 59 million tonnes per annum (in 2008).  Virtually every producers use the chloralkali process which includes the electrolysis of sodium chloride using one of three cell types: mercury, diaphragm, or membrane.  If this process is used, 1.1 tonnes of caustic soda can be produced to each tonne of chlorine.


Storage and Distribution

Caustic Soda Pearls are stored and transported inside 25 kg woven bags with a PE liner.  For transportation purposes they are classed as packing group II, hazard class 8 as well as they are corrosive and can cause burns.  They have a specific gravity of 2.13.


Caustic soda pearls are an important inorganic chemical as they are used in numerous industries worldwide.  The highest demand for caustic soda comes from the paper industry where it is utilised in pulping as well as bleaching procedures.  They are also in demand in the aluminium industry as the caustic soda dissolves bauxite ore, which is the raw material inside aluminium production.  An additional main use for caustic soda is chemical processing as caustic soda is a vital feedstock for a series of down-stream products including solvents, plastics, fabrics, adhesives etc.

Caustic soda pearls are also used in soap production as they engender saponification of the vegetable oils or fats that are necessary for soap manufacture.  They also have in role inside the natural gas industry where sodium hydroxide is used to support produce and process petroleum products.  Caustic soda can also be employed in the textile industry where it is used in the chemical processing of cotton.

Caustic Soda Pearls also has small scale applications.  It can also be used for aluminium etching, chemical analysis, and inside paint stripper.  It is also a component in a range of domestic products including pipe and drain cleaner, oven cleaner, and inside home-cleaning products.
