[China Aluminum Network] 1. What types of non-ferrous metals can be divided into several categories according to their characteristics?
A: Non-ferrous metals can be classified into heavy metals, light metals, precious metals, rare metals, and semi-metals according to certain characteristics. Aluminum is a kind of metal of colored light metals.
2. What is the raw material for aluminum electrolysis?
A: The raw materials for aluminum electrolysis are roughly divided into three categories: raw materials—aluminum oxide; flux—fluoride salt; anode material—pre-carbonization.
3, the history of aluminum can be divided into two stages?
A: The chemical method of aluminum and electrolytic aluminum are two stages.
4. What is the purpose of aluminum electrolysis into direct current?
Answer: The direct current is fed into the electrolytic cell. On the one hand, the thermal energy is used to melt the cryolite into a molten state and maintain a certain electrolysis temperature. On the other hand, the main purpose is to realize an electrochemical reaction at the two electrodes, that is, to make the electrolyte. The aluminum ions in the electrons are deposited on the cathode to obtain aluminum, and the oxygen ions are discharged on the anode to form a mixed gas of carbon dioxide and carbon dioxide.
5. What is electrolysis of aluminum?
A: Electrolytic aluminum is a cryolite-alumina molten salt electrolysis method. It uses cryolite as a solvent, alumina as a smelting substance, and a strong direct current flowing into the electrolytic cell to perform an electrochemical reaction on the cathode and the anode. Electrolysis products, the cathode is aluminum liquid, the anode is CO2 and CO gas, this method is electrolytic aluminum.
As we all know,stainless steel is an internationally recognized health material that can be implanted into the human body, so stainless steel as the main material of kitchen and bathroom supplies have begun to popular in Europe and the United States.
