Boehmite

Product Detail

Boehmite or böhmite  is an aluminium oxide hydroxide (?-AlO(OH)) mineral, a component of the aluminium ore bauxite. It is dimorphous with diaspore.It is white with tints of  yellow, green, brown or red due to impurities. It has a vitreous to pearly  luster, a Mohs hardness of 3 to 3.5 and a specific gravity of 3.00 to 3.07. It  is colorless in thin section, optically biaxial positive with refractive indices  of na = 1.644 – 1.648, nß = 1.654 – 1.657 and n? = 1.661 – 1.668.

Boehmite occurs in tropical laterites and bauxites developed on  alumino-silicate bedrock. It also occurs as a hydrothermal alteration product  of corundum and nepheline. It occurs with kaolinite, gibbsite and diaspore in  bauxite deposits; and with nepheline, gibbsite, diaspore, natrolite and  analcime in nepheline pegmatites.[3] Industrially, it is used as an inexpensive  flame retardant additive for fire-safe polymers.
 We could manufacture and adjust boehmite as your required data.
