Storage conditions
1. It should be stored in a cool and dry warehouse. Keep the packaging sealed to prevent damage. During transportation, it is necessary to prevent rain, sunlight, and moisture.
Stability
1. Stable at room temperature and pressure
2. Materials to avoid: moisture/moisture. Slightly soluble in water and hot ethanol, insoluble in cold ethanol. It begins to decompose during melting. It can be decomposed by strong acids such as sulfuric acid to produce boron trifluoride. When fused with alkali metal carbonates, fluoride and borate are generated. Toxic!
White powder or gel shaped crystal, non hygroscopic, bitter in taste, can be crystallized from aqueous solution to obtain hexagonal prism crystal. Slightly soluble in water and hot ethanol, insoluble in cold ethanol. The melting point is 530 ℃, and it begins to decompose during melting. It can be decomposed by strong acids such as sulfuric acid to produce boron trifluoride. When fused with alkali metal carbonates, fluoride and borate are generated. The density of potassium fluoborate is 2.498g/cm3. Toxic. Rat abdominal LD50240mg/kg.
3. It can be decomposed into boron trifluoride by strong acids. Co melting with alkali metal carbonates generates fluoride and borate. Toxic.
