Alumina Ceramics:
Alumina ceramics is a process in which an anode is placed in an electrolyte solution, and an aluminum oxide film is formed on the surface by electrolysis, which is called anodizing treatment of an aluminum plate. The cathode in the device is a material having high chemical stability in an electrolytic solution, such as Lead, stainless steel, aluminum, etc. The principle of aluminum anodization is essentially the principle of water electrolysis. When the current passes, hydrogen is evolved on the cathode; on the anode, the oxygen evolved is not only molecular oxygen but also atomic oxygen. (O) and ionic oxygen, usually expressed as molecular oxygen in the reaction. The aluminum as the anode is oxidized by the oxygen deposited on it to form an anhydrous aluminum oxide film, and the generated oxygen does not all act on aluminum, and part of it is in a gaseous state. Form of precipitation.
Selection of Oxidation Electrolytic Solution for Alumina Sheet: A prerequisite for the growth of anodized film is that the electrolyte should have a dissolution effect on the oxide film. However, this does not mean that anodization can generate an oxide film or generate in all electrolytes in which dissolution exists. The oxide film has the same properties.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
