1 Control the composition ratio of electrolytic refining agent When using electrolytic refining agent, it is especially important to ensure the content of Na3AIF6. Of course, NaCI cannot be used to replace KCI. The purpose of ensuring the content of Na3AIF6 is to reduce the wetting angle between the slag particles in the melt and the medium, [...]
As mentioned above, the gas content and slag content in the electrolytic aluminum body melt are far greater than those in the remelted aluminum liquid. The solubility of the gas dissolved in the aluminum liquid decreases as the temperature of the melt decreases. During the casting or rolling process, the melt cools rapidly and solidifies into a solid, [...]
1 Characteristics of electrolytic aluminum liquid Electrolytic aluminum liquid is produced by high-temperature electrolysis of aluminum oxide in the presence of certain electrolytes (such as cryolite, etc.) using a special process. The temperature of electrolytic aluminum liquid is generally between 920 and 950°C, and the residence time in the tank is long. The aluminum liquid is extracted from the [...]
1 Types of aluminum-based solid solutions in electrolytic capacitor aluminum foil Aluminum foil for electrolytic capacitors usually needs to be made of high-purity aluminum. However, even the highest purity aluminum inevitably contains a small amount of impurity elements. Sometimes it is necessary to artificially add a small amount of alloying elements to the aluminum foil for [...]
1. Vacancy Capacitors - other defects in aluminum Vacancies in aluminum crystals are defects caused by missing atoms in normal positions in the structure. Vacancies can cause local distortions in the crystal structure, which are limited to a few atomic distances. Relative to the scale of the entire crystal, the spatial range involved in vacancies is [...]
