Zinc borate is a flameretardant additive used in polymer, wood, and textile products. There are different types of zinc borate with different chemical compositions and structures, one of these is crystalline zinc borate with the formula 2ZnO·3B 2 O 3 · 2 O. This form of zinc borate is usually produced by reaction of zinc oxide and boric acid under appropriate temperature and mixing
