Why is aluminum more expensive than silver in history

One reason:
In ancient times, the production technology of aluminum was very backward, so the working time of aluminum was longer than that of silver, so aluminum was more expensive than silver in the market.
Two. Analysis:
At that time, the refining technology of aluminum metal was not good, the price of aluminum was more expensive than silver, so people used to use aluminum products as the honor to show their status. Napoleon, the French emperor, is a man who likes to show off. He often banquets and banquets all the guests. He always puts on a superior look at every party. Almost all the utensils on the table were made of silver, and the only bowl he used was aluminum products.
It turned out that in the Napoleon era almost 200 years ago, smelting and using gold and silver had a long history. However, at that time, people just learned that aluminum can be smelted from bauxite, and the technology of smelting aluminum is still very backward. Smelting aluminum is very difficult.
Therefore, aluminum was very rare at that time. Not to mention the fact that the common people could not afford it. Napoleon asked guests to use silver tableware, just to use their own aluminum bowls, just to show their dignity and dignity.
It must be ridiculous to get it now, because today, aluminum is much cheaper than silver, and its luster and performance are far less than silver. Aluminum became cheaper because people later invented the technology of electrolytic aluminum, which can produce aluminum in large quantities. The main raw material of aluminum smelting is the earth's large reserves of bauxite. The production technology of aluminum, which is rich in raw materials, enough in electricity and efficient, has made the output of aluminum rise rapidly, and aluminum has become a very common thing.
