Metal Cations as Inorganic Structure-Directing Agents for the Preparation of Zeotype Aluminosilicates (Case No. 2022-246)

Summary UCLA researchers have developed a method for directing the crystallization of aluminosilicate materials into either phillipsite zeolite or tobermorite silicate hydrate phases—using specific ratios of sodium (Na⁺), potassium (K⁺), and calcium (Ca²⁺) cations in synthesis gels, without organic structure-directing agents (OSDAs). Background Zeolites...

Vaterite Synthesis via Portlandite Carbonation (Case No. 2022-182)

Summary UCLA researchers have developed a process to manufacture stable vaterite, a calcium carbonate polymorph, by carbonating portlandite under mild conditions and using stabilizers to prevent its conversion to more stable forms. The resulting material can be used as a cement replacement to help reduce embodied carbon in concrete systems. Background Ordinary...
