Hydrolysis Of

In the present investigation, the Al-C-KCl composite powders were prepared by a ball milling processing in an attempt to improve the hydrogen evolution capacity of aluminum in water. The results showed that the hydrogen generation reaction is affected by KCl amount, preparation processing, initial aluminum particle size and reaction temperature. Increasing KCl amount led to an increased hydrogen generation volume. The use of aluminum powder with a fine particle size could promote the aluminum hydrolysis reaction and get an increased hydrogen generation rate. The reaction temperature played an important role in hydrogen generation rate and the maximum hydrogen generation rate of 44.8 cm3 min-1g-1of Al was obtained at 75oC. The XRD results identified that the hydrolysis byproducts are bayerite (Al(OH)3) and boehmite (AlOOH).

This work aimed on the granulometric characterization of flotation products and to analyze the effect of the variables (that were investigated in a flotation work) on the particle size distribution parameters. Besides to compare the parameter values of the granulometric analysis for the concentrate and tailing both results were compared with the parameter values of the flotation feed samples. The analyzed parameters showed lower values for the concentrate products as compared with the parameters for tailing and feed samples. For coarse and fine particle size fractions the column height was the variable that more influenced on the parameter values.

The Cost

The mechanical properties of porcelain are strongly influenced by the generated thermal stress during processing. When quartz particle size is reduced its influence on the technical properties of ceramic products such as tiles and porcelains are changed. In this work, the properties of triaxial ceramics materials were evaluated using quartz of different particle size distribution. It was reported strong variations in mechanical strength and thermal shock strength. Although the cost of milling is increased to reduce quartz particle size, it can be compensated by its implicit advantages. The experimental results were very interesting showing the way that quartz particle size influences the analyzed properties. A significant improving in porcelain strength and thermal strength was obtained.
