Hyun Sook Lee, Tai Hwan Ha, Kwan Kim (2005): "Fabrication of unusually stable amorphous calcium carbonate in an ethanol medium". ''Materials Chemistry and Physics'', volume 93, issues 2–3, pages 376-382. {{doi|10.1016/j.matchemphys.2005.03.037}} "Herein we report that amorphous calcium carbonate (ACC) is in fact readily formed in an ethanol medium [from calcium chloride and ammonium carbonate]. More importantly, we found that ACC formed by the method under discussion is kinetically stabilized by incorporating ammonia during its formation in ethanol. "As described in the Experimental section, a gel-like precipitate is formed in ethanolic solution of CaCl2 as CO2 vapor diffuses into the solution; shown in Fig. 1(a), a milky-white solution gradually settles into a gel-like precipitate, and upon shaking it turns back to a milky-white solution."
