Zinc borate (chemical formula: 2ZnO · 3B ₂ O3 · 3.5H ₂ O) is an important inorganic compound that is widely used in flame retardant, anti-corrosion, ceramic and other fields due to its unique chemical properties.

Zinc borate is an inorganic compound widely used in coatings, plastics, rubber, ceramics, and other fields. In recent years, with the continuous expansion of its application in flame retardant, anti-corrosion and other fields, there has been an increasing discussion on the safety of zinc borate.

The chemical formula of zinc borate is 2ZnO · 3B2O3 · 3.5H2O, with a molecular weight of 434.51 and a melting point of 980 ℃. It is a white or light yellow powder that is insoluble in water, but may decompose in acidic or alkaline environments. Due to its low water solubility and high thermal stability, zinc borate is sensitive to humidity and temperature during storage.

Anhydrous Zinc Borate is a zinc borate compound without crystalline water, with the chemical formula 2ZnO · 3B2O3. Compared with common hydrated zinc borate, anhydrous zinc borate exhibits significant advantages in the field of flame retardant materials due to its unique chemical structure and physical properties.
