Patent number: 8470280Abstract: The invention discloses a method of preparing monodisperse microtablets of calcium carbonate in aqueous solutions containing calcium, gelatin and urea. Calcium carbonate powders of a unique tablet-like morphology were produced by simply ageing the prerefrigerated (at 4° C. for at least 24 hours) CaCI2-gelatin-urea solutions at 70° C. for 24 h in ordinary glass media bottles. Thermal decomposition of dissolved urea was used to supply aqueous carbonate (CO32?) ions to the calcium (Ca2+) ion and gelatin-containing solutions. Monodisperse CaCO3 microtablets have the particle sizes from 1 to 8 microns. CaCO3 microtablets were biphasic in nature and consist of 93 to 98% vaterite and 2 to 7% calcite. Identical solutions used without prerefrigeration yielded only trigonal prismatic calcite crystals upon ageing at 70° C. for 24 h.Type: GrantFiled: August 3, 2007Date of Patent: June 25, 2013Inventor: Ahmet Cüneyt Tas
