Abstract: A method of forming a crystalline Boehmite product for use in a coating that includes preparing an aqueous slurry by mixing together water, pseudo-Boehmite, and aluminum material configured to dissolve in alkaline solution, followed by performing a hydrothermal process using the slurry to form the crystalline Boehmite. The mass ratio of pseudo-Boehmite to aluminum material in the slurry is = 30% with the slurry having an overall solid content of = 50%. The crystalline Boehmite, pseudo- Boehmite, and aluminum material each have an average (D50) primary particle size and an average (D50) secondary particle size. The average (D50) secondary particle size of aluminum material is 77.4 micrometers (µm); the average (D50) secondary particle size of pseudo-Boehmite is 8.0 µm, the average (D50) secondary particle size of crystalline Boehmite product is 5.0 µm, and an average (D50) secondary particle size/an average (D50) primary particle size ratio 3.0.
