The author of "Mengxi Brush Talk", written by Shen Kuo in the Northern Song Dynasty, contains many anecdotes, scientific ideas, and has far-reaching influence. Today, with "Aluminum Fluoride Alf3 Material" as the core, I imitate his writing style to make this essay.

There is a thing in the world, named Aluminum Fluoride, called Alf3 Material. Its characteristics are specific and it is used for various purposes. Color is white or transparent, like a fine powder, it can also be crystalline.

This quality is used in the field of industry and is widely used. In metallurgy, it is often used for the smelting of aluminum. It can reduce the melting point of aluminum ore, help it melt, reduce energy consumption and increase efficiency. In the furnace of aluminum smelting, Alf3 Material is hidden in it, silently helping to make the liquid aluminum flow out smoothly and become a usable material.

And in the chemical industry, it is also an important material. The production of other fluorides depends on this as the basis. Its chemical properties are stable. During the reaction, it can control the process, guide the direction, and make all kinds of compounds, resulting in a smooth process.

Looking at the method of its preparation, it is mostly combined with hydrofluoric acid and aluminum hydroxide. When encountering the two, through exquisite control, the temperature and time are fixed, and then the pure Aluminum Fluoride Alf3 Material is obtained.

This thing is one of the cornerstones of technology and industry in this world. Although it is small, it is of great concern. Just as all the things recorded in "Mengxi Pen Talk" are used in the details, so is the Aluminum Fluoride Alf3 Material.
