Open Data Verified Data
white crystals. Usually contains 2, 4 and 6 water of crystallization. The relative density was 2. 120. Soluble in water and alcohol. Water of crystallization was lost at 60 °c. Hydrate-like ammoniacal compounds can be formed. This complex is heat-labile and easily decomposes reversibly to metal fluorides, ammonia, ammonium fluoroborate, and boron ammoniumfluoride. Deliquescence. Toxic.

ZINC FLUOROBORATE - Preparation Method
Open Data Verified Data
fluoroboric acid zinc carbonate method: boric acid and hydrofluoric acid reaction to produce fluoroboric acid, and then with zinc carbonate reaction, control the pH value of 3~4. The impurities were removed by filtration, and the solution was evaporated under reduced pressure (60-70 ° C.) to precipitate crystals, and then dried to obtain a finished zinc fluoroborate product.
