Liquid amorphous calcium phosphates

Precipitates Drugs prepared by separating particles from a previously clear liquid by physical or chemical means. Precipitation usually occurs when a hot saturated solution of an amorphous substance is allowed to cool or when a liquid in which the dissolved substance is insoluble is added to its solution. Pharmacists formerly used the process of precipitation as a convenient method of obtaining solid substances in fine particles (precipitated calcium carbonate), to purify solids (precipitated calcium phosphate), or to prepare mercury salts. White precipitate (ammoniated mercury) was first described by Beguin in 1632, a soluble double chloride of mercury and ammonium known to the alchemists as sal alembroth and sal sapientiae, respectively. Red precipitate (red mercuric oxide) was known to alchemists as hydragyrum preci-pitatum per se or precipitate per se yellow precipitate is a synonym for yellow mercuric oxide.
