PARTICULAS DE HIDRATO DE ALUMINA E PROCESSO PARA SUA PREPARACAO |
摘要 |
Alumina hydrate particles have a high surface area and low dispersity and may have a low soluble soda content. They may be made by milling a liquid suspension of alumina hydrate, subjecting the milled suspension to classification into coarse and fine fractions, recycling the coarse fraction to the mill and recycling the fine fraction to the classification stage. A narrow particle size distribution is obtained. |
