Open Data Verified Data
1. Zinc oxide method
Put a certain proportion of zinc oxide and boric acid into a crystallizer pre placed with boric acid, and react for 5-7 hours at 80-100 ℃. Then filter, wash, dry, crush, and prepare the finished zinc borate product.
2. Zinc hydroxide method
In the presence of water and other organic solvents, zinc hydroxide and boric acid are added to the reactor. React at 100 ℃ for 6-10 hours. The solid obtained after filtration is washed with hot water and dried to obtain the finished zinc borate product.
