Patent number: 11235979Abstract: Disclosed is a method for manufacturing crystals of aluminates of one or more element(s) other than aluminium, referred to as “A. The method includes: placing starting reagents, including at least one aluminium element source and a source of the element(s) A that has a degree of oxidation of between 1 and 6, in suspension in a liquid medium, forming a suspension referred to as the “starting suspension”; milling the starting suspension at ?50° C., in a three-dimensional liquid medium ball mill for ?5 minutes; recovering, at the outlet of the three-dimensional ball mill, a suspension referred to as the “end suspension” including the starting reagents in activated form or crystals of aluminate of the element(s) A generally in hydrated form; if required, calcination of the end suspension when it includes the starting reagents in activated form, to obtain generally non-hydrated crystals of aluminate of the element(s) A.Type: GrantFiled: October 5, 2017Date of Patent: February 1, 2022Assignee: EASYLInventors: François Lacoste, Valentin Lair, Julien Thiel, Samy Halloumi

Patent number: 10941094Abstract: A method for manufacturing calcium diglyceroxide crystals includes at least the following steps: placing at least one calcium element source compound, in particular calcium oxide, in suspension in glycerol or in a homogeneous mixture of glycerol and an anhydrous solvent of glycerol, in particular methanol, referred to as the “starting suspension”, the molar ratio being greater than or equal to 2; milling the starting suspension at an ambient temperature of less than or equal to 50° C. in a three-dimensional liquid-phase ball mill for a holding time of 15 minutes or less; recovering, at the outlet of the mill, a suspension of calcium diglyceroxide crystals, and optionally, washing the obtained suspension with a glycerol solvent in order to eliminate any excess glycerol, optionally, drying the suspension of calcium diglyceroxide crystals so as to obtain a powder of calcium diglyceroxide crystals. Also disclosed are uses associated with the calcium diglyceroxide crystals.Type: GrantFiled: September 29, 2017Date of Patent: March 9, 2021Assignee: EASYLInventors: François Lacoste, Valentin Lair, Julien Thiel, Samy Halloumi

Patent number: 10472248Abstract: Disclosed is a method for manufacturing calcium zincate crystals including: placing calcium hydroxide2 and zinc oxide, one of the precursors thereof, or one of the water mixtures thereof in a starting suspension, the mass ratio of water to calcium hydroxide and zinc oxide, or one of the precursors or mixtures thereof, being greater than or equal to 1; milling the starting suspension to an ambient temperature less than or equal to 50° C. in a wet-phase three-dimensional micro-ball mill for a residence time less than or equal to 15 minutes and in particular from 5 to 25 seconds; recovering a calcium zincate crystal suspension coming out of the mill; and optionally, concentrating or drying the calcium zincate crystal suspension so as to obtain a calcium zincate crystal powder. Also disclosed are uses associated with the calcium zincate crystals obtained according to the method described above.Type: GrantFiled: March 31, 2016Date of Patent: November 12, 2019Assignee: EASYLInventors: Francois Lacoste, Julien Thiel
