Application areas

The result of producing boehmite with the hydrothermal method is a crystalline aluminum oxide hydroxide, which is used as a catalyst in the oil industry. Aluminum oxides are gaining in importance as an environmentally friendly refractory material without halogen elements in polymers, which are treated at higher temperatures. Boehmites are stable at high temperatures and optimal for use in electric thermal insulation elements
