  Potassium - LoveToKnow 1911
Potassium hydroxide or caustic potash, KOH, formerly considered to be an oxide but shown subsequently to be a hydroxide of potassium, may be obtained by dissolving the metal or monoxide in water, but is manufactured by double decomposition from potassium carbonate and slaked lime: K 2 CO 3 -E-Ca(OH) 2 =2KOH+CaC03.
Potassium carbonate, K 2 CO 3, popularly known as "potashes," was originally obtained in countries where wood was cheap by lixiviating wood ashes in wooden tubs, evaporating the solution to dryness in iron pots and calcining the residue; in more recent practice the calcination is carried out in reverberatory furnaces.
Potassium sulphate, K2S04, a salt known early in the 14th century, and studied by Glauber, Boyle and Tachenius, was styled in the 17th century arcanum or sal duplicatum, being regarded as a combination of an acid salt with an alkaline salt.

The alkaline earth metal oxide dispersion is in contact with the internalsmoisture content of the potassium bicarbonate substrate, and with the potassium carbonate crystallites residing on the potassium bicarbonate particle surface.
An essential aspect of the present invention is the in situ formation of alkaline earth metal carbonate on the potassium bicarbonate particle surface, and the consequential adherent bonding of the alkaline earth metal carbonate coating to the underlying particle surface.
The potassium carbonate is present as crystallites on the surface of the potassium bicarbonate particles.

 BeeSource.com | POV | Joe Traynor | MAKING "K" PAY IN YOUR VINEYARD Dripping Potassium Carbonate into the ...
Potassium carbonate can't compete with lime on a cost basis, nor can it compete as a potassium fertilizer, however the combination fertilizer/amendment properties of potassium carbonate make it an intriguing material for raising soil pH on drip-irrigated crops with a high potassium requirement, such as bearing vineyards.
Potassium carbonate is hygroscopic and will clump as it picks up moisture from the air, however the 50-pound bags in which it is sold minimizes this problem.
Bearing vineyards have a high potassium requirement with an estimated 100 pounds or more of potassium removed each year by the crop, and in situations where both a pH boost and a nutritional boost were needed, water-run potassium carbonate could be the ideal answer, especially for drip-irrigated plantings.

A eutectic mixture of lithium carbonate and potassium carbonate in a ratio of 62 mole %/38 mole % is commonly used in molten carbonate fuel cells (MCFC) as an electrolyte.
The re-deposition of preferentially transported potassium carbonate results in an irreversible alteration of the 62/38 molar ratio of the eutectic mixture of the lithium potassium carbonate electrolyte.
It is a further object of the present invention to provide means to eliminate the potential for the preferential transport of potassium carbonate and subsequent irreversible alteration of the 62/38 molar ratio of the eutectic mixture of the lithium potassium carbonate electrolyte.

 Potassium carbonate - Wikipedia, the free encyclopedia
Potassium carbonate is a white salt, soluble in water (insoluble in alcohol), which forms a strongly alkaline solution.
Potassium carbonate was first identified in 1742 by Antonio Campanella and is the primary component of potash and the more refined pearlash or salts of tartar.
The resulting potassium hydroxide is then carbonated using carbon dioxide to form potassium carbonate, which is often used to produce other potassium compounds.

 Calcium Chloride and Potassium Carbonate   (Site not responding. Last check: 2007-10-21)
Calcium chloride and potassium carbonate both are able to dissolve in water quite well.
This is because their crystal lattices are not stable enough to resist the ability of water to surround and stabilize ions.
The calcium and carbonate ions prefer being in the lattice to being disoolved in water, so the solid will form when calcium and carbonate are present.
