Drinking water treatment Calcined lime is use to soften water by removing carbonate and noncarbonate hardness. This purifies the water for consumption, provides better tasting water and allows soap products to lather readily. Industrial waste water treatment Lime can be used in industrial waste water treatment to soften process or boiler feed water, precipitate metals and nonmetals and to ...

Feb 01, 2008 · Phosphate addition resulted in precipitation of hopeite (22%), while calcination induced formation of spinels, gahnite (44%), and franklinite (34%). Although calcination was previously used to agglomerate phosphate phases by sintering, we found that it formed sparingly soluble Zn phases.

Betatricalcium phosphate (βTCP) was never synthesized directly using an aqueous method. Asprecipitated powder from a wet chemical method needs to undergo a heattreatment process (or calcination) to enable the intermediate phase (s) to be transformed into singlephase TCP. In this work, calcium hydroxide, (Ca (OH)2), and phosphoric acid, (H3PO4), were mixed as the precursor materials .
