Fast Fabrication of Superhydrophobic Surfaces on Aluminum by the Comibined Method of Chemical and Electrochemical Corrosion

A ICP-MS method for the determination of 5 trace impurity elements of copper, titanium, zinc, manganese and cobalt in aluminum has been developed in this paper.

Based on the formula of aluminum bonded unburned Al2O3-C slide gate plates,mixtures of corundum、metal aluminum、flake graphite and thermosetting phenolic resin binder were prepared,and then formed、dried、cut and finally grinded into 25 mm × 25 mm× 130 mm samples.

Matrix Effect and Determination of Impurity Elements in Aluminium;

Usually aluminium is dissdved in dilute sulfuric acid slowly.

The Effect of Aluminium Content on the Property Aluminium Titanate-Aluminium Nitride-Alumina Composite

Study on the metal aluminum dissolvability experiment

The sample is dissolved by Cu 2Cl 2-NH 4Cl,Cu 2Cl 2-NH 4Cl was chosen as the selective solvent for Aluminium metal in this study, which solved common problem of the separation of Aluminium metal and Al 2O 3.

potash fertilizer, Aluminium metal, soda ash and cement, etc.

Using 80%～90% tabular corundum and 10%～20% Al as the main material, a multiphase Al-AlN-Al_2O_3 material whose main crystalline phase is corundum and the bond phases are Al and AlN can be prepared by nitridation-sintering at 1 100 ℃ and surface oxidation treatment under 800 ℃.
