Boehmite - Uses and synthesis methods
background
Boehmite is an important precursor material for preparing alumina with different crystal forms. It is widely used in adsorption separation, catalysis, composite materials, liquid crystal, medicine, optics, sensors and other fields. In recent years, with the upgrading of diaphragm technology war, the domestic have predicted the boehmite coating market opportunity.
Introduction
Boehmite is also called boehmite, and its molecular formula is & gamma;-AlOOH(& gamma; The monohydrate alumina of the phase belongs to the orthorhombic system and has a layered structure. In each single structural layer, oxygen ions are arranged in cubic close packing at the apex of the octahedron, aluminum ions are located in the center of the octahedron to form a double-layer structure, hydroxide is located on the surface of the layered structure, and the layers are connected by hydrogen bonds..
structural characteristics
Boehmite is usually a white crystal powder, but due to the impurities it contains, it often shows yellow, with a Mohs hardness of 3~3.5 and a specific gravity of 3~3.07. Due to its unique crystal structure and morphology, boehmite has the characteristics of zero charge, high interface free energy, large porosity, large specific surface area, good dispersibility, good glue solubility, and high heat resistance. It is widely used in industrial production.
method of synthesis
Boehmite is a metastable phase of thermodynamics, which is easy to dehydrate to form aluminum oxides at high temperatures. At present, there are many synthesis methods of boehmite, including microemulsion method, sol-gel method, electrochemical method, steam-assisted dry gel conversion method and steam-assisted wet gel conversion method.
