What is the chemical name of this compound?
This compound is called ferrous carbonate, which is an iron-containing compound with a chemical formula of $FeCO_ {3} $.
Ferrous carbonate is usually a white triangular crystal in appearance. It is quite stable in dry air, but it is easily oxidized in wet air, and then forms a hydrate of iron hydroxide, which turns yellow-brown in color.
In ancient times, although there was no modern chemical understanding as accurate as this, the properties of many minerals and compounds have also been observed and applied. Ferrous carbonate is commonly found in siderite in nature. When ancient people mined, they may have noticed this substance.
In terms of chemical properties, ferrous carbonate can react with acids. Taking hydrochloric acid as an example, the chemical equation of the reaction is $FeCO_ {3} + 2HCl = FeCl_ {2} + H_ {2} O + CO_ {2}\ uparrow $. In this reaction, ferrous carbonate interacts with hydrochloric acid to form ferrous chloride, water and carbon dioxide gas.
Furthermore, ferrous carbonate decomposes under heating conditions to form ferrous oxide and carbon dioxide, that is, $FeCO_ {3}\ stackrel {heated }{=\!=\!=} FeO + CO_ {2}\ uparrow $. If heated continuously, ferrous oxide will further react with oxygen in the air to form more stable iron oxides.
In ancient smelting technology, although no specific mature process was formed for the refining of ferrous carbonate, the process of processing iron-bearing ores may also involve chemical reactions related to ferrous carbonate. Because of its decomposition product ferrous oxide, it can further participate in the smelting process of iron and play a certain role in obtaining metallic iron.

What are its chemical properties?
The chemical properties of a substance are related to its properties and changes in chemical reactions. The following is described in detail in the form of ancient proverbs.
One, flammability. If the substance is flammable, it can react violently with oxygen in the event of open flame, high temperature and other conditions, and it can occur in light and heat. Such as firewood, which contains elements such as hydrocarbons, which can be burned in sufficient oxygen and can be turned into carbon dioxide, water, etc., and emits a lot of heat energy for cooking, heating, etc.
Its dioxide, oxidation and reduction. Those with oxidation can take away electrons from other substances in the reaction and oxidize them. For example, oxygen is often a strong oxidant. Iron gradually rusts in the air because iron is oxidized by oxygen. Those with reducing properties are willing to lose electrons and reduce other substances. Such as hydrogen, it can reduce copper oxide to copper under heating conditions and turn itself into water. This is due to the reducing properties of hydrogen.
Third, acid and alkali. Acidic substances can release hydrogen ions in water, which can neutralize with alkalis, and raw salts and water. Such as acetic acid, which has the general nature of acid, can react with metals to release hydrogen and react with calcium carbonate to dissolve. Basic substances release hydroxide ions in water, which can also neutralize with acids. Such as slaked lime, it can be used to improve acidic soils because of its alkalinity.
Fourth, stability. Some substances are chemically stable and do not easily react chemically at room temperature and pressure. Such as gold, which does not corrode for a long time, due to its high chemical stability, it is difficult to react with other substances. Some substances have poor stability, such as hydrogen peroxide, which can gradually decompose into water and oxygen at room temperature.
Fifth, corrosive. Strong acids and alkalis are corrosive and can corrode other substances. Such as concentrated sulfuric acid, which can dehydrate and carbonize organic matter, touch the skin, and can cause serious burns. Another example is sodium hydroxide solution, which can also corrode a variety of materials, so be careful when using it.
What fields is this compound used in?
This synthetic product is useful in all kinds of fields. In the war of the army and the army, it can be used as a firearm aid. In the past, the battle formation, with its medicinal power erupted, the power of firearms was greatly increased, or it was a sharp weapon for siege and breaking barriers, or it became a good tool for defending against the enemy and attacking the invaders.
In the field of medicine, it also has its merits. With its characteristics, doctors can make a cure. In case of a golden wound, or a medicine for removing blood stasis and building muscles; in case of internal diseases and miscellaneous diseases, or it can reconcile the viscera, remove evil and correct, and save the people from the pain.
It is also indispensable in the craftsmanship of Baigong. Craftsmen make utensils, which can be used to help temper metals, making utensils more tough and sharp; potters make pottery, which can be used to add color and luster, making pottery glowing and exquisite.
In the realm of farming, it can also be beneficial. Applied to the fields, or to fertilize the fields and fertile soil, to help the growth of crops, so that the five grains are abundant, the barns are enriched, and the food of the people can be provided.
In the school of alchemy and monastery, it is also an important thing. Alchemists use it to participate in refining, hoping to prolong life and exude the wonders of immortality. Although this path is mysterious and unpredictable, it does have a place in the method of alchemy.
From this perspective, this synthetic product is used in many fields such as the military, medicine, industry, agriculture, and Taoism. It can be used as a soldier to kill the enemy, or as a medicine to cure and save people, or as an essence of aids, or as a rich harvest, or as a member of alchemy. It has a great impact on all things in the world.
What are the methods for synthesizing this compound?
The method of synthesizing this thing is quite complicated, and it is described in detail below.
First, it is necessary to find suitable raw materials. This raw material should have a specific texture and character, and it may have reserves in mountains and rivers. As recorded in ancient times, some spiritual minerals are buried deep underground, and after years of precipitation, they absorb the essence of heaven and earth, and then they have usable qualities. When exploring, you need to follow the veins of mountains and rivers and the weather of the veins to determine its location.
Second, the control of the heat is crucial. If you want to make this thing, you must refine it with a special heat. The fire should not be too strong or too weak. If it is too prosperous, the raw materials will be easy to coke and lose their true nature; if it is too weak, it will be difficult to make them blend, and the purpose of synthesis will not be achieved. In the past, there were famous swordsmiths who used three flavors of real fire, supplemented by spiritual charcoal, to observe the color of the flame, listen to the sound of the fire, and accurately grasp the heat, and finally become a peerless sword. The same is true for synthesizing this thing.
Third, the method of reconciliation is indispensable. Mixing all kinds of raw materials in a specific ratio is like blending an elixir. The slightest difference is a thousand miles away. It is necessary to follow the formula recorded in ancient books and measure accurately to make the raw materials blend with each other in order to maximize its effectiveness. For example, Shennong tasted all kinds of herbs, understood the properties of all kinds of medicines, and used them together to heal all people. The synthesis of these compounds also needs to understand the properties of each raw material and be reasonably reconciled.
Fourth, the creation of the environment is also exquisite. At the time of synthesis, the surrounding environment should be quiet and peaceful, free from external interference. Or in a deep cave, or at the top of a mountain, where there is abundant spiritual energy, it is more conducive to synthesis. The ancient immortals often chose caves, heaven and earth, and borrowed the spiritual energy of heaven and earth to help the formation of medicinal pills. The synthesis of this substance should also choose such good places.
In short, the synthesis of this substance requires caution in many aspects such as raw materials, heat, harmony, and environment before it can be successful.
