TECHNICAL DETAILS
Chemical and Physical Properties
Molecular weight: 61.83 g/mol
Specific gravity: 1.50
Appearance: Free-flowing, white, crystal line granules or powder
Solubility: 5.46% boric acid by weight in saturated solution (water) at room temperature
Stability: Optibor is a stable crystalline product that does not change chemically under normal storage conditions. Wide fluctuations in temperature and humidity can cause recrystallization at particle contact points, resulting in caking. Care should be taken to avoid such fluctuations during product storage and to maintain the integrity of the packaging.
Bulk density: 55 lb/ft3 (881 kg/m3)
Angle of repose: 33°
Chemical Composition (Theoretical)
Boric oxide, B2O3: 56.30%
Water of crystallization, H2O: 43.70%
Containers: Grades may be available in bulk, IBCs, or small bags
