The melting point of gold is 1064.18 ° C, and the boiling point is 2856 ° C; the melting point of the silver is 961.78 ° C, and the boiling point is 2212 ° C; the melting point of copper is 1083.4 ° C, and the boiling point is 2562 ° C; the melting point of the iron is 1538 ° C, and the boiling point is 2750 ° C. The monocular (free form of free state) of gold is commonly referred to as gold. It is a popular precious metal. It has been used for currency, value preservation and jewelry for many centuries. In nature, gold appears in the golden blocks or golden grains, underground ore veins and accumulation layers in the rock. Igly is one of the metals known and used in ancient times, and it is an important precious metal. Silver has a single quality in nature, but most of them exist in silver ore in the form of compliance. The nature of silver is relatively stable, with good thermal conductivity and electrical conductivity, soft and extensible. Pure copper is a soft metal. When the surface is cut, it is red and orange with metal luster, and the single matter is purple -red. Good ductility, high thermal conductivity and high electrical conductivity. Therefore, cables, electrical and electronic components are the most commonly used materials. It can also be used as architectural materials and can form many alloys. Copper alloy has excellent mechanical properties and low resistance, the most important bronze and brass. It pure iron is white or silver -white, with metal luster. The melting point is 1538 ° C and the boiling point is 2750 ° C. It can solve the strong acid and medium -intensive acid, insoluble in water. Iron has a 0 price, 2 price, 3 price and 6 price, of which 2 and 3 are more common, and the 6 price is rare. The expansion information:
The use of gold is: 1. For international reserves This is determined by the gold currency product attribute of gold. Due to the excellent characteristics of gold, the function of gold as currency in history, such as value scale, circulation means, storage methods, payment methods and world currencies. After the decoupling of gold and the US dollar since the 1970s, the monetary functions of gold have also weakened, but they still maintain a certain monetary function. 2, used as jewelry decoration gorgeous gold jewelry has always been a symbol of a person's social status and wealth. 3. Application in industrial and science and technology It because gold has a unique and good properties, it has extremely high corrosion stability; good conductivity and thermal conductivity; the atomic nucleus of the gold has a nucleus in the gold. The effective section of the neutron is larger; the reflection capacity of the infrared rays is close to 100%; it has various touch -media properties in the alloy of gold. Reference materials Source:
Methods 1 1 In a melted gold. You need the right device to melt gold.器 is a specially designed container that can be contained in melting gold and can withstand high temperatures. 是 is usually made of graphite carbon or clay. The melting point of gold is about 1064 ° C, which means that it must be melted to melt it. Therefore, choosing a container is important. [1] In addition to 坩埚, you also need to mobilize and fix 坩埚. The tongs are also heat -resistant. If you do n’t have a cricket, there is a temporary method to use potatoes. When using this method, dig a hole in potatoes and put gold in. 2 The welding to remove gold impurities. The welding agent is a substance to be added before melting gold, and it is usually mixed with borax and sodium carbonate. If of the gold, more welded agents are needed. There are many different formulas for welding mixtures. There is a way to mix borax and sodium carbonate. Two small groups of mixtures are added to pure gold per 30 grams. If the jewelry is dirty, you can add a little more. Ordinary baking soda purchased by the store can form sodium carbonate after heating. [4] The welds can gather small golden particles and remove impurities in gold during heating. When melting with the potato method, a pinch of borax should be added to the dig hole before heating. 3 The safety at all times. Because the temperature required for melting gold is very high, it is very dangerous. If you have no experience in melting gold at all, please consult a professionals first. Find a safe place at home to melt gold, such as garage or empty room. You have to prepare a workbench to place the materials. Ben must be worn on the goggles and masks to protect the face. In addition, you have to wear heat -resistant gloves and tie thick apron. , do not melt gold next to flammable materials. This is very dangerous, causing the fire to be definitely not the result you want to see. Methods 2 1 This electric furnace used to melt gold. This is a small high -energy kiln that is used to melt precious metals including gold and silver, which can be bought online. The price of some electric furnaces is very cheap. The electric furnace can also be used to mix and melt metal at home (such as gold, silver, copper, aluminum, etc.). The use of the same equipment is also required to use the electric furnace, such as 坩埚 and welding. If the gold also contains a small amount of silver, copper or zinc, the melting point will be reduced. 2 This to melt gold with a microwave oven with 1200 watts. The magnetic control tube of the microwave oven is best on both sides or behind, not on the top. It you can buy microwave alchemy equipment or kiln. Put the kiln on the kiln rack of the microwave oven. Put the gold in the cricket during heating, place it in the kiln, and cover it. If the microwave oven was used to melt gold, don't use it to heat the food. Methods 3 1 This to melt the gold with a propane spray gun. As mentioned earlier, be careful when using a spray gun. However, the spray gun can melt gold in only a few minutes. gold should be placed in the middle of the pupa. Then, put the 在 on the surface of a fire prevention, and use the spray gun to directly accommodate the gold in the 坩埚. If you are using a spray gun, you can add the pyrocratic compound to gold first, so that the slightly lower temperature can melt it. The small golden powder in the 小 is easy to blow away, so be careful when the spray gun is approaching.开 Heating is too fast to crack, so you have to heat it slowly. The speed of fusion of gold by oxygen acetylene spray gun is faster than propane spray guns. The flames of spray guns at the top of the gold powder, and slowly turn the circle to heat. When the powder starts to rise and turn red, the spray gun can be slowed down until the powder becomes a gold block. 2 Mushing the melted gold. Think about how to deal with melting gold. Maybe you want to sell it in a new form, you can try to make gold ingots or other shapes, such as gold bars. Preded into the gold ingot mold or other molds before the melting gold coagulation, and then waited for it to cool. The mold should be made of similar materials. don't forget to clean up! Don't leave high -temperature things that are not managed or placed where the child can get.
