Abstract[English]
The present disclosure provides a process for producing borate crystals and the resultant granular borate composition formed from the process. In an embodiment, the process includes (a) providing an aqueous solution comprising from 3 wt% to 6 wt% of boron in a reaction vessel, and (b) heating the aqueous solution to a high temperature from 70°C to 90°C. The process includes (c) seeding, at the high temperature, the aqueous solution with one or more particles of a borate to form a seeded solution, (d) cooling the seeded solution at a rate from 0.1°C/hr to 4°C/hr to a low temperature that is from 4°C to 10°C less than the high temperature and forming borate crystals in the seeded solution, (e) repeating steps (a)-(d) at least once, and (f) forming wet borate crystals having a particle size from 18 U.S. mesh to 4 U.S. mesh.[French]
La présente divulgation propose un processus de production de cristaux de borate et la composition de borate granulaire résultante formée à partir du processus. Dans un mode de réalisation, le processus consiste à (a) fournir une solution aqueuse comprenant 3 % en poids à 6 % en poids de bore dans une cuve de réaction, et à (b) chauffer la solution aqueuse à une température élevée de 70 °C à 90 °C. Le processus consiste à (c) ensemencer, à haute température, la solution aqueuse avec une ou plusieurs particules d'un borate pour former une solution ensemencée, à (d) refroidir la solution ensemencée à une vitesse de 0,1 °C/h à 4 °C/h à une température basse qui est 4 °C à 10 °C inférieure à la température élevée et à former des cristaux de borate dans la solution ensemencée, à e) répéter les étapes (a) à (d) au moins une fois, et à (f) former des cristaux de borate humides possédant une taille de particule de 18 mesh (norme américaine) à 4 mesh (norme américaine).
