Descripción general

El producto es un óxido de aluminio activado básico (Alúmina, Al2O3) que tiene un grado de actividad Brockman I. Se ha estudiado el mecanismo de formación de las escamas protectoras de α-Al2O3 en las superficies de aleaciones binarias de M-Al (M = Fe, Ni o Co) a elevadas temperaturas. Los óxidos de aluminio activados que tienen diferentes acideces y concentraciones de agua (con una actividad de Brockmann de I a V) pueden detectar fácilmente varios tipos de agua (agua libre, agua de los poros y agua ligada) en el óxido de aluminio presente en los suelos.
Los óxidos de aluminio Brockmann son adecuados para cromatografía en columna y filtración adsortiva.

Aplicación

El óxido de aluminio (alúmina) se ha utilizado para la retirada de los peróxidos del disolvente de deshidratación (tetrahidrofurano, THF) en un protocolo. El protocolo consistía en el estudio de alta resolución de la anatomía fina del cerebro en cerebros de ratón marcados con fluorescencia.
Puede utilizarse en la fabricación de electrólitos sólidos policristalinos de yoduro de litio-óxido de aluminio. La incorporación del óxido de aluminio aumentó de manera notable la conductividad del yoduro de litio.
