Acid-base propertyEthanol dehydration reactionEthanol-TPDThe acid-base properties of Al 2 O 3 with various surface characteristics were studied by XRD, HR-TEM, ethanol TPD, and ethanol dehydration reaction rate measurements. Ethanol TPD showed that the desorption temperature (at maximum rate of ...
-Alumina and boric acid are important constituents in all types of low expansion glasses for chemical ware, cooking, and thermometers. -The presence of alumina in silicate glass reduces phase separation. -There is a case where higher alumina content can actually encourage crystal growth (Anorthite ...
