Patent number: 11161783Abstract: A composition and process for manufacture thereof used in hybrid inventive building materials comprising Syngenite (K2Ca(SO4)2.H2O) and Struvite-K (KMgPO4.6H2O). Starting constituents include magnesium oxide (MgO), monopotassium phosphate (MKP) and stucco (calcium sulfate hemihydrate), mixed in predetermined ratios, cause reactions to proceed through multiple phases, which reactions variously are proceeding simultaneously and in parallel. Variables, e.g., water temperature, pH, mixing times and rates, have been found to affect resultant reaction products. Preferred ratios of chemical constituents and manufacturing parameters, including predetermined weight percent and specified ratios of Struvite-K and Syngenite are provided for building products used for specified purposes. Reactions are optimized in stoichiometry and additives to reduce the combined heat of formation to non-destructive levels. Various additives help control and guide reactions.Type: GrantFiled: November 18, 2019Date of Patent: November 2, 2021Assignee: CertainTeed Gypsum, Inc.Inventors: Robert J. Hauber, Gerald D. Boydston, Nathan Frailey, Severine Lamberet, Gaurav V. Pattarkine, Isaac K. Cherian, Sergio Centurione, Anirban Ghosh

Patent number: 10472284Abstract: A composition and process for the manufacture thereof for use in a hybrid building material comprising at least in part Syngenite (K2Ca(SO4)2.H2O) and Struvite-K (KMgPO4ยท6H2O). Specified constituents, including magnesium oxide (MgO), monopotassium phosphate (MKP) and stucco (calcium sulfate hemihydrate) are mixed in predetermined ratios and the reaction proceeds through multiple phases reactions which at times are proceeding simultaneously and in parallel and reaction may even compete with each other for reagents if the Struvite-K reaction is not buffered to slow down the reaction rate). A number of variable factors, such as water temperature, pH mixing times and rates, have been found to affect resultant reaction products. Preferred ratios of chemical constituents and manufacturing parameters, including predetermined and specified ratios of Struvite-K and Syngenite may be provided for specified purposes, optimized in respect of stoichiometry to reduce the combined heat of formation to non-destructive levels.Type: GrantFiled: August 17, 2016Date of Patent: November 12, 2019Assignee: CertainTeed Gypsum, Inc.Inventors: Robert J.
