If it is other chemical components of the salts, we must speak to their specific trade names or chemical names, such as soda ash, baking soda, red alum, ammonium sulfate, potassium nitrate, potassium chloride, diammonium phosphate, etc., must can not be generally called "industrial salt" or "chemical salt."

如果是其他化学成分的盐类，一定要说出其特定的商品名称或化学名称，如纯碱、小苏打、红矾、硫酸铵、硝酸钾、氯化钾、磷酸氢二铵等，绝不能笼统叫"工业盐"或者"化工盐"。

Ultrafine γ-Al 2O 3 particles were prepared by thermal decomposition of ammonium alum .

Increasing the calcining temperature at 1500℃ 5h, the morphologies of the product became the big and wide vermiform-fiber form particles, the length was about 2.5 μm, and the width was about 700 nm. In addition, the vermiform-fiber form particle could be found in the filtrated precipitate with the additional ammonium sulfate. If the ratio of ammonium sulfate to alum is above 1, the vermiform-fiber form particle was formed. After calcined at 1500℃ 5h, the particle grow up to 2μm. Adding ammonium sulfate was also reduced the particles size of alumina because the surface area of the products was increased by increasing the quantity of ammonium sulfate.

在明矾与氨水沉淀物经过滤后再额外添加不同硫酸铵的比例，1200℃ 1hr煅烧后，发现添加硫酸铵比例在1以上，其型态亦为蠕虫状纤维，当以1500℃ 5hr煅烧，蠕虫状纤维型态粒子亦变为又大又胖，其粒子尺寸长度约为 2 μm 宽度约为 500 nm；且将煅烧1200℃ 1hr测其比表面积值，会随著硫酸铵的添加量增加，粉体的表面积会增加且粉体变细，添加硫酸铵比例为 4 者所得粉体粒径最小，从比表面积所得结果估计约 150 nm 。
