Abstract
A boehmite structure includes a plurality of boehmite particles where adjacent boehmite particles are bonded to each other. The boehmite structure has a porosity of 30% or less. A method of producing a boehmite structure includes obtaining a mixture by mixing hydraulic alumina with a solvent including water, and pressurizing and heating the mixture under a condition of a pressure of 10 to 600 MPa and a temperature of 50 to 300° C.
Claims12
A boehmite structure, comprising:
- a plurality of boehmite particles where adjacent boehmite particles are bonded to each other,
- wherein the porosity in a cross section of the boehmite structure is 20% or less, and
- an average particle diameter of the boehmite particles making up the boehmite structure is from 300 nm to 50 μm.
