TRANSMISSION ELECTRON MICROSCOPY SHOWED THAT XEROGEL OF LONG AND SHORT FIBROUS BOEHMITE SAMPLES, ALO(OH), WERE RESPECTIVELY PRODUCED VIA HYDROLYSIS OF ALUMINIUM ALKOXIDE AT SLOW AND HIGH STIRRING RATES. THERMOGRAVIMETRY, DIFFERENTIAL SCANNING CALORIMETRY, AND X-RAY DIFFRACTOMETRY, SHOWED THE TWO XEROGELS TO PRODUCE SIMILAR CALCINATION PRODUCTS, AT 400±C AND UP TO 1000±C, FOR THE CHEMICAL AND PHASE COMPOSITION OF THE MATERIAL BULK. ... إقراء المزيد
