The structure and the forming process of SO42-/ZrO2-SiO2 catalysts were investigated by TG and DTA. The restraint of silica to the crystallization of the catalysts and the relations of weight loss temperature and loss amount of sulfur oxide bonded to the surface of the catalysts with the contents of zirconia were revealed by experimental results. The forming process of the catalysts was also explored by these techniques, some very important information, which will be useful for understanding the structure and properties of catalysts, were obtained.
