Experimental Study on the Influence of Temperature on Surface Characteristics of Alkaline Residue
A series of laboratory experiments on the change characteristic of BET surface area and pore size of alkaline residue(Huaian) under different temperatures were carried, the experimental procedure and results are described and analyzed in this study. The BET surface area of alkaline residue decrease obviously with temperature increasing, and the decresing tendency is slowly after 600°C. The experiment resluts show that 600°C is a threshold of alkaline residue BET surface area change. Pore size slowly increases with temperature rising. In the experimental study, alkaline residue surface morphology is researched by SEM under different temperature, SEM images showed that alkaline residue is porous polymeric aggregate in natural conditon, there is an improtant influence of thermal treatment on alkaline residue surface morphology. The porous aggregate is more compact, and its pore gradually increses with temperature rising.
